Description

The Microchip Technology Inc. MCP1525/41 devices

are 2.5V and 4.09 6V precis ion vol tage references that

use a combination of an advanced CMOS circuit

design and EPROM trimming to provide an initial

tolerance of ±1% (max.) and temperature stability of

±50 ppm/°C (max.). In addition to a low quiescent

current of 100 µA (max.) at 25°C, these devices offer a

clear advantage ov er the traditional Zener tech niques

in term s of stability across time and temper ature. The

output voltage is 2.5V for the MCP1525 and 4.096V for

the MCP1541. These devices are offered in SOT-23-3

and TO-92 packages, and are specified over the

industrial temperature range of -40°C to +85°C.

1.1.1 OUTPUT VOLTAGE

Output voltage is the reference voltage that is available

on the output pin (VOUT).

1.1.2 INPUT VOLTAGE

The input (operating) voltage is the range of voltage

that can be applied to the VIN pin and still have the

device produce the designated output voltage on the

VOUT pin.

1.1.3 OUTPUT VOLTAGE DRIFT (TCVOUT)

The output te mperature coefficient or voltage drift is a

measure of how much the output voltage (VOUT) will

vary from its initial value with changes in ambient

temperature. The value specified in the electrical

specifications is measured and equal to:

1.1.4 DROPO UT VOLTAGE

The dropout voltage of these devices is measured by

reducing VIN to the point where the output drops by 1%.

Under these conditions the dropout voltage is equal to:

EQUATION 1-2:

The dropout voltage is affected by ambient

temperature and load current.

In Figure 2-18, the dropout voltage is shown over a

negative and positive range of output current. For

currents above zero milliamps, the dropout voltage is

positive. In this case, the voltage reference is primarily

milliamps, the dropout voltage is negative. As the

output current becomes more negative, the input

current (IIN) reduces. Under this condition, the output

current begins to provide the needed power to the

voltage reference.

1.1.5 LINE REGULATION

Line regulation is a measure of the change in output

voltage (VOUT) as a function of a change in the input

voltage (VIN). This is expressed as VOUT/VIN and is

measured in either µV/V or ppm. For example, a 1 µV

change in VOUT caused by a 500 mV change in VIN

would net a VOUT/VIN of 2 µV/V, or 2 ppm.

1.1.6 LOA D REGULATION (VOUT/IOUT)

Load regulation is a measure of the change in the

output voltage (VOUT) as a function of the change in

output current (IOUT). Load regulation is usually

measured in mV/mA.

1.1.7 INPUT CURRENT

The input current (operating current) is the current that

sinks fr o m VIN to VSS without a l oad current on the out-

put pin. This current is affec ted by temperature and the

output current.

1.1.8 INPUT VOLTAGE REJECTION

RATIO

The Input Vol tage Rejection Ratio (IVRR) is a measure

of the change in output voltage versus the change in

input voltage over frequency, as shown in Figure 2-7.

The calculation used for this plot is:

EQUATION 1-3:

1.1.9 LONG-TERM OUTPUT STABILITY

The long-term output stability is measured by exposing

the devices to an ambient temperature of 125°C

(Figure 2-9) while configured in the circuit shown in

Figure 1-1. In this test, all electrical specifications of the

devices are measured periodically at +25°C.

FIGURE 1-1: Dynamic Life Test

Configuration.

1.1.10 OUTPUT VOLTAGE HYSTERESIS

The output voltage hysteresis is a measure of the

output voltage error once the powered devices are

cycled over the entire operating temperature range.

The amount of hysteresis can be quantified by

measuring the change in the +25°C output voltage after

temperature excursions from +25° C to + 85°C to +25°C

and also from +25°C to -40°C to +25°C.

3.0 PIN DESCRIPTIONS

Descriptions of the pins are listed in Table 3-1.

TABLE 3-1: PIN FUNCTION TABLE.

3.1 Input Voltage (VIN)

VIN functions as the positive power supply input (or

operating inpu t). An optional 0.1 µF ceram ic capacitor

can be placed at this pin if the input voltage is too noisy;

it needs to be within 5 mm of this pin. The input voltage

needs to be at least 0.2V higher than the output voltage

for normal operation.

3.2 Output Voltage (VOUT)

VOUT is an accurate reference voltage output. It can

source and sink small currents, and has a low output

impedance. A load capacitor betw een 1 µF and 10 µF

needs to be located within 5 mm of this pin.

3.3 Ground (VSS)

Normally connected directly to ground. It can be placed

at another voltage as long as all of the voltages shift

with it, and proper bypassing is observed.

4.0 APPLICATIONS INFORMATION

4.1 Application Tips

4.1.1 B ASIC CIRCUIT CONFIGURATION

The MCP1525 and MCP1541 voltage reference

devices should be applied as shown in Figure 4-1 in all

applications.

FIGURE 4-1: Basic Circuit Configuration.

As shown in Figure 4-1, the input voltage is connected

to the de vice at the VIN input, with an optional 0.1 µF

ceramic ca pacitor. T his capacitor woul d be required if

the input voltage has excess noise. A 0.1 µF capacitor

would reject input voltage noise at approximately

1 to 2 MHz. Noise below this frequency will be amply

rejected by the input voltage rejection of the voltage ref-

erence. Noise at frequencies above 2 MHz will be

beyond the bandwidth of the voltage reference and,

consequently, not transmitted from the input pin

through the device to the output.

The load capacitance (CL) is required in order to

stabilize the voltage reference; see Section 4.1.3

“Load Capacitor”.

4.1.2 INPUT (BYPASS) CAPACITOR

The MCP1525 and MCP1541 voltage references do

not require an input capacitor across VIN to VSS.

However, for added stability and input voltage transient

noise reduction, a 0.1 µF ceramic capacitor is

recommended, as shown in Figure 4-1. This c apacitor

should be close to the device (within 5 mm of the pin).

4.1.3 LOA D CAPACITOR

The output capacitor from VOUT to VSS acts as a

frequency compensation for the references and cannot

be omitted. Use load capacitors between 1 µF and

10 µF to compensate these devices. A 10 µF output

capacitor has slightly better noise, and provides

additional charge for fast load transients, when

compared to a 1 µF output capacitor. This capacitor

should be close to the device (within 5 mm of the pin).

4.1.4 PRINTED CIRCUIT BOARD LAYOUT

CONSIDERATIONS

Mechanical s tress due to Printed Ci rcuit Board ( PCB)

mounting can ca use the output voltage to shift from its

initial value. Devices in the SOT-23-3 package are

generally more prone to as sembly str ess than de vices

in the TO-92 package. To re duce str ess-related output

voltage shifts, mount the reference on low-stress areas

of the PCB (i.e., away from PCB edges, screw holes

and large components).

4.1.5 OUTPUT FILTERING

If the noise at the output of these voltage references is

too high for the particular application, it can be easily

filtered with an external RC filter and op amp buffer.

The op amp’s input and output voltage ranges need to

include the reference output voltage.

FIGURE 4-2: Output Noise-Reducing

Filter.

The RC filter values are selected for a desired cutoff

frequency:

EQUATION 4-1:

The values that are shown in Figure 4-2 (10 k and

1 µF) will create a first-order, low-pass filter at the

output of the amplifier. The cutoff frequency of this filter

is 15.9 Hz, and the attenuation slope is 20 dB/decade.

The MCP6021 amplifier isolates the loading of this low-

pass filter from the remainder of the application circuit.

This amplifier also provides additional drive, with a

faster resp onse time than the voltage reference.

4.2 Typical Application Circuits

4.2.1 NEGATIVE VOLTAGE REFERENCE

A negative precision voltage reference can be

generated by us ing the MCP1525 or MCP1541 in the

configuration shown in Figure 4-3.

FIGURE 4-3: Negative Voltage

Reference.

In this circuit, the voltage inversion is implemented

using the MCP606 and two equal resistors. The voltage

at the output of the MCP1525 or MCP1541 voltage

reference drives R1, which is connected to the inverting

input of the MCP60 6 amplifie r. Since the non-inverting

input of the a mplifier is biased to g round, the inv erting

input will also be close to ground potential. The second

10 k resistor is placed around the feedback loop of

the amplifier. Si nce the inverting input of the amplifier is

high-im pedance, the current gener ated through R1 will

also flow through R2. As a consequence, the output

voltage of the amplifier is equal to -2.5V for the

MCP1525 and -4.1V for the MCP1541.

4.2.2 A/D CONVERTER REFE RENCE

The MCP152 5 and MC P1541 were c arefully de signed

to provide a voltage reference for Microchip’s 10-bit

and 12-bit families of ADCs. The circuit shown in

Figure 4-4 shows a MCP1541 configured to provide the

reference to the MCP3201, a 12-bit ADC.
