AP1150ADSXX
14V Input / 200mA Output LDO Regulator
1. Genaral Description
The AP1150ADSxx is a low dropout linear regulator with ON/OFF control, which can supply 200mA load
current. The IC is an integrated circuit with a silicon monolithic bipolar structure. The output voltage, trimmed
with high accuracy, is available from 1.3 to 9.5V in 0.1V steps.
The output capacitor is available to use a small 0.1uF ceramic capacitor (1.8VVout). The over current, thermal
and reverse bias protections are integrated, and also the package is small and thin type. The IC is designed for
space saving requirements.

11.2 Input / output capacitors
Linear regulators require input and output capacitors in order to maintain the regulator's loop stability. The
equivalent series resistance (ESR) of the output capacitor must be in the stable operation area. However, it is
recommended to use as large a value of capacitance as is practical. The output noise and the ripple noise
decrease as the capacitance value increases. ESR values vary widely between ceramic and tantalum capacitors.
However, tantalum capacitors are assumed to provide more ESR damping resistance, which provides greater
circuit stability. This implies that a higher level of circuit stability can be obtained by using tantalum capacitors
when compared to ceramic capacitors with similar values.
For output voltage device 2.0V applications, the recommended value of CL0.10F.
For output voltage device 1.5V applications, the recommended value of CL0.22F
