TYPICAL APPLICATION

The APU8852 device is an efficient linea

voltage regulator with better than 2% initial

voltage accuracy, very low dropout voltage and

very low ground current designed especially fo

hand held, battery powered applications. Othe

features of the device are: TTL compatible

enable/shutdown control input, current limiting

and thermal shutdown.

The APU8852 is available in fixed and

adjustable output voltage versions in a small

SOT-23 5-Pin package.

Unless otherwise specified, these specifications apply over CIN=CO=2.2F, IO=100A, VIN(MIN)=2.5V(Adjustabledevices)

VIN=VO+ 1V(for fixed voltage devices), VOUT=VFB(for adjustable version only), CBYP=470pF(for fixed voltage

devices), VEN=2V and TA=25oC. Typical values refer to TA=25oC. Low duty cycle pulse testing is used which keeps

unction and case temperatures equal to the ambient temperature.

Note 1: Low duty cycle pulse testing with Kelvin connections is required in order to maintain accurate data.

Note 2: Dropout voltage is defined as the minimum differential voltage between VIN and VOUT required to maintain regulation at VOUT. It is

measured when the output voltage drops 1% below its nominal value.

Note 3: Ground current is the regulator quiescent current plus the pass transistor current. The total current from the supply is the sum of the load

current plus the ground pin current.

PIN DESCRIPTIONS

PIN SYMBOL PIN DESCRIPTION

The input pin of the regulator. Typically a large storage capacitor is connected from

this pin to ground to insure that the input voltage does not sag below the minimum

drop out voltage during the load transient response. This pin must always be higher

than VOUT by at least the amount of the dropout voltage and some margin in order

for the device to regulate properly.

Ground pin. This pin must be connected to the lowest potential in the system and

all other pins must be at higher potential with respect to this pin.

Enable pin. A low signal or left open on this pin shuts down the output. This pin

must be tied HI or to VIN for normal operation.

Adj (Adjustable only) A resistor divider from this pin to the VOUT pin and ground sets the output voltage.

CBYP (Fixed only) A 470 to 1000pF bypass capacitor connected to this pin reduces the output noise.

The output of the regulator. A minimum of 2.2uF with max ESR of 1Ω capacitor

must be connected from this pin to ground to insure stability.
