APL5155E
High Input Voltage, Low Quiescent Current, 150mA LDO Regulator
Features
General Description
• Wide Input Voltage Range: 4. 5V to 25V
The APL5155E is a low ground current linear regulator,
• Ultra Low Ground Current: 10µA
which operates with input voltage from 4. 5V to 25V and
• High Output Accuracy: ±2. 5%
delivers output current up to 150mA. Typical dropout volt-
• Excellent Load/Line Transient
age is only 750mV at 150mA loading. This combination
• Low Dropout Voltage: 750mV @ 150mA
of the high voltage and the low ground current makes the
APL5155E ideal for USB and portable devices, using 2• Fixed Output Voltages for 5V/3. 3V or Adjustable
cell or 3-cell Li-Ion battery inputs.
Voltage
The APL5155E is stable with aluminum, tantalum, and
• Built-In Current-Limit Protection
ceramic capacitors. It requires a 1µF or greater capacitor
• Built-In Over-Temperature Protection
for stability.
• Zero Shutdown Current
The APL5155E has many protection functions, including
• Internal Soft-Start Function
over-temperature, current-limit and short circuit current
• POR Scheme to Prevent VOUT Spike • SOT-23-5, SOT-89, and SOP-8P Packages • Lead Free and Green Devices Available
(RoHS Compliant)
limit protections, which prevent the device from thermal over-load and current over-load. The APL5155E regulator is available in miniature SOT23-5, SOT-89, and SOP-8P packages.
