Features
General Description
The AP7201 is a dual low-dropout (LDO) CMOS linear regulator.
The device operates from 1.9V to 5.5V input and delivers up to
150mA per output channel.
• Wide input voltage range: 1.9V – 5.5V
• Low dropout voltage: 100mV at 100mA output current
• Very low quiescent current (Iq): 25uA typical
• Fixed output voltage: 1.0V to 3.3V
The AP7201 includes a pass element, voltage reference, error
amplifier, current limit and built-in phase compensation. Key
features include individual logic-compatible enable/shutdown
control inputs, fold-back current limit and thermal shutdown
protections.
• Up to 150mA per output channel
• Very fast transient response
• High PSRR: 78dB at 1kHz
• Accurate voltage regulation
• 300mA current limiting
• Thermal shutdown protection
The AP7201 is fully compatible with low ESR ceramic capacitors,
reducing cost and improving output stability. The fixed output
voltage for each channel is set independently. Voltages are
100mV per step within a range of 1.0V to 3.3V.
• Ambient temperature range -40ºC to 85°C
• Package available: DFN2018-6 (USP-6B)
• DFN2018-6 (USP-6B): Available in “Green” Molding
Compound (No Br, Sb)
• Lead Free Finish / RoHS Compliant (Note 1)
The EN function allows the output of each channel to be turned
off independently, resulting in greatly reduced power
consumption. The AP7201 is available in the DFN2018-6
(USP-6B) package.
Applications
• Bluetooth Headsets
• Cell Phones
• Digital Still Cameras
• Smart Phones and PDA
• GPS
• MP3/MP4
• PMP
