AP7167
1.2A LOW DROPOUT REGULATOR WITH POK
Features
Description
• 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
• DFN3030-10: Available in “Green” Molding Compound
(no Br, Sb)
• Lead Free Finish/RoHS Compliant (Note 1)
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.
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.
Built-in current-limit and thermal-shutdown functions prevent IC
from damage in fault conditions. The AP7167 is available in
DFN3030-10 package.
Applications
• Servers and laptops
• Smart phone and PDA
• MP3/MP4
• Bluetooth headset
• Low and medium power applications
• FPGA and DSP core or I/O power
