-Preliminary- AP1159ADSXX
14V Input / 100mA Low voltage Output LDO Regulator
1. General Description
The AP1159ADSXX is a low dropout linear regulator with ON/OFF control, which can supply 100mA load
current. The IC is an integrated circuit with a silicon monolithic bipolar structure. The output voltage, trimmed
with high accuracy, is available from 0.9 to 1.2V in 0.1V steps. The output capacitor is available to use a small
0.47μF ceramic capacitor. The over current, thermal and reverse bias protections are integrated, and also the
package is small and thin type, SOT23-5. The IC is designed for space saving requirements.

Power dissipation
PD - 400 mW (Note 1)
Note 1. Ambient temperature is over 25C, power dissipation decreases by 4.0mW/C. In case of mounting on
2 layer glass epoxy substrate (3cm×3cm, t=1mm, cupper layer t=0.35μm)
WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal
operation is not guaranteed at these extremes.
