General Description
The AP160 family is a positive voltage linear
regulator developed utilizing CMOS technology
featured low quiescent current (30µA typ.), low
dropout voltage, and high output voltage accuracy.
Built-in low on-resistance transistor provides low
dropout voltage and large output current. A 2.2µF
or greater can be used as an output capacitor.
The SOT-89 and SOT-223 packages are attractive
for “Pocket” and “Hand Held” applications.
These robust devices are designed to prevent
device failure under the worst operation condition
with both Thermal Shutdown and Current
Fold-back.
Applications
- Battery-powered Devices
- Personal Communication Devices
- Home Electric / Electronic Appliances
- PC Peripherals
