APL5320
Ultra-Low-Noise, High PSRR, Low-Dropout, 300mA Linear Regulator
Features
General Description
• Wide Operating Voltage: 2.5~6V
The APL5320 is a P-channel low dropout linear regulator
• Low Dropout Voltage: 290mV @ 3V/300mA
which needs only one input voltage from 2.5 to 6V, and
• Fixed Output Voltages: 1.2~3.7V with Step 100mV, delivers current up to 300mA to set output voltage. It also
and 2.85V, 4.75V
can work with low ESR ceramic capacitors and is ideal for
• Guaranteed 300mA Output Current
• High PSRR: 70dB
• Current-Limit Protection
using in the battery-powered applications such as note-
book computers and cellular phones. Typical dropout volt-
age is only 290mV at 300mA loading.
The APL5320 provides several versions of fixed output
• Controlled Short-Circuit Current: 50mA
voltages ranging from 1.2 to 3.7V with step 100mV and
• Over-Temperature Protection
2.85V, 4.75V. Current-limit with current foldback and ther-
• Stable with 1µF Capacitor for Any Load
mal shutdown functions protects the device against cur-
• Excellent Load/Line Transient
rent over-loads and over-temperature. The APL5320 is
• SOT-23-5, TSOT-23-5, SOT-23-3, SC-70-5, available in SOT-23-5, TSOT-23-5, SOT-23-3, SC-70-5,
