APE8800A

TYPICAL APPLICATIO

The APE8800A is a low dropout, positive linear

regulator with very low quiescent current. The APE8800A

can supply 300mA output current with low dropout voltage

at about 250mV. The BP pin with a 10nF bypass capacitor

can help reduce the output noise level. The shutdown

function can provide remote control for the external signal to

decide the on/off state of APE8800A. With a logic high level

at SHDN pin, the device is in the on state, and vice versa.

The APE8800A regulator is able to operate with output

capacitors as small as 1µF for stability. Other than the

current limit protection, APE8800A also offers the on chip

thermal shutdown feature providing protection against

overload or any condition when the ambient temperature

exceeds the maximum junction temperature.

The APE8800A offers high precision output voltage of

+2%. It is available in fixed output voltages including 1.2V,

1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.1V, 3.3V, 3.6V, 4.5V and

5.0V. The APE8800A is housed in low-profile, space-saving

SOT-23-5L & TSOT-23-5L package.

Note：To prevent oscillation, it is recommended to use minimum 1µF X7R or X5R dielectric capacitors if

ceramics are used as input/output capacitors.

PIN DESCRIPTIONS

PIN SYMBOL

Power is supplied to this device from this pin which is required an input filter capacitor. In general, the input

capacitor in the range of 1µF to 10µF is sufficient.

The output supplies power to loads. The output capacitor is required to prevent output voltage from oscillation.

The APE8800A is stable with an output capacitor 1µF or greater. The larger output capacitor will be required for

application with larger load transients. The large output capacitor could reduce output noise, improve stability,

and PSRR.

APPLICATION INFORMATI

Output & Input Capacitor

Protection Features

Thermal Consideration

Shutdown Operation

APE8800A

The APE8800A is a low dropout linear regulator that could provide 300mA output current at

dropout voltage about 250mV. Current limit and on chip thermal shutdown features provide

protection against any combination of overload or ambient temperature that could exceed maximum

junction temperature

The APE8800A regulator is designed to be stable with a wide range of output capacitors. The

ESR of the output capacitor affects stability. Larger value of the output capacitor decreases the

peak deviations and improves transient response for larger current changes.

The capacitor types (aluminum, ceramic, and tantalum) have different characterizations such

as temperature and voltage coefficients. All ceramic capacitors are manufactured with a variety of

dielectrics, each with different behavior across temperature and applications. Common dielectrics

used are X5R, X7R and Y5V. It is recommended to use 1uF to 10uF X5R or X7R dielectric ceramic

capacitors with 30mΩ to 50mΩ ESR range between device outputs and ground for stability. The

APE8800A is designed to be stable with low ESR ceramic capacitors and higher values of

capacitors and ESR could improve output stability. The ESR of output capacitor is very important

because it generates a zero to provide phase lead for loop stability.

There are no requirements for the ESR on the input capacitor, but its voltage and temperature

coefficient have to be considered for device application environment.

In order to prevent overloading or thermal condition from damaging the device, APE8800A has

internal thermal and current limiting functions designed to protect the device. It will rapidly shut off

PMOS pass element during overloading or over temperature condition.

The power handling capability of the device will be limited by maximum operation junction

temperature. The power dissipated by the device will be estimated by PD = IOUT x (VIN-VOUT). The

power dissipation should be lower than the maximum power dissipation listed in “Absolute Maximum

Ratings” section.

The APE8800A is shutdown by pulling the SHDN input low, and turned on by driving the SHDN

high. If this function is not used, the SHDN input should be tied to VIN to keep the regulator on at all

times (the SHDN must not be left floating).
