Introduction
The MAX8885 is a low-dropout, low-quiescent-current linear regulator designed primarily for battery-powered applications using low-cost, high-ESR tantalum capacitors. The device delivers up to 150mA and is available with preset output voltages of 2.5V, 2.7V, 3.0V, 3.3V, or 5.0V. The MAX8885 consists of a 1.25V reference, error amplifier, P-channel pass transistor, power-OK comparator, and internal feedback voltage divider. The 1.25V bandgap reference is connected to the error amplifier’s inverting input. The error amplifier compares this reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the reference voltage, the pass-transistor gate is pulled lower, which allows more current to pass to the output and increases the output voltage. If the feedback voltage is too high, the pass-transistor gate is pulled up, allowing less current to pass to the output. The output voltage is fed back through an internal resistor voltage divider connected to the OUT pin. Additional blocks include a current limiter, reverse-battery protection, thermal sensor, and shutdown logic.
Features
- Operates from a +2.5V to +6.5V input voltage range and delivers up to 150mA
- Uses a P-channel MOSFET pass transistor to allow a low 85µA supply current, independent of the load and LDO voltage
- Optimized to operate with low-cost, high-ESR output capacitors such as small case-size tantalum capacitors
- Features a power-OK output that indicates when the output is out of regulation
- Available in preset output voltage versions of 5.0V, 3.3V, 3.0V, 2.7V, and 2.5V
- 1µA (max) shutdown current
- Short-circuit protection
- Thermal shutdown protection
- Reverse-battery protection
- Available in a miniature 5-pin SOT23 package
- Pin Compatible with MIC5206
- Undervoltage Power-OK Output
- Preset Output Voltages (±1% accuracy)
- Guaranteed 150mA Output Current
- 85µA No-Load Supply Current
- Low 110mV Dropout at 100mA Load (165mV at 150mA load)
- Thermal-Overload and Short-Circuit Protection
- Reverse-Battery Protection
- 60dB PSRR at 100Hz
- 1µA max Shutdown Current
