AP7167
1.2A LOW DROPOUT REGULATOR WITH POK
Description
Features
The AP7167 is a 1.2A, adjustable output voltage, ultra-low
dropout linear regulator. The device includes pass element, error
amplifier, band-gap reference, current limit and thermal shutdown
circuitry. The device is turned on when EN pin is set to logic high
level. A Power-OK (POK) output is available for power
sequence control.

Wide input voltage range: 2.2V – 5.5V
230mV very low dropout at 500mA load
500mV very low dropout at 1A load
Very low quiescent current (IQ): 125µA typical
Adjustable output voltage range: 0.8V to 5.0V
Very fast transient response
High PSRR
Accurate voltage regulation
Current limiting and short circuit protection
Thermal shutdown protection
Stable with any type output capacitor ≥ 4.7µF
Ambient temperature range -40ºC to 85°C
The characteristics of the low dropout voltage and low quiescent
current make it suitable for low to medium power applications, for
example, laptop computers, audio and video applications, and
battery powered devices. The typical quiescent current is
approximately 125µA.
DFN3030-10: Available in “Green” Molding Compound
(no Br, Sb)
Lead Free Finish/RoHS Compliant (Note 1)
Built-in current-limit and thermal-shutdown functions prevent IC
from damage in fault conditions. The AP7167 is available in
DFN3030-10 package.
