Overview
- Power-OK Output
- Small Output Capacitor (1µF ceramic)
- 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
The MAX8875 low-dropout linear regulator operates from a +2.5V to +6.5V input range and delivers up to 150mA. A P-channel MOSFET pass transistor allows its 85µA supply current to remain independent of the load, making this device ideal for battery-operated portable equipment such as PCS phones, cellular phones, cordless phones, and modems.
The MAX8875 features a power-OK output that indicates when the output is out of regulation. The device is available in several preset output voltage versions: 5.0V, 3.3V, 3.0V, 2.7V, 2.5V, or 1.5V. Other features include 1µA (max) shutdown current, short-circuit protection, thermal shutdown protection, and reverse-battery protection. The device comes in a miniature 5-pin SOT23 package.
The MAX8875 is optimized for use with a 1µF ceramic output capacitor. For a pin-compatible, functionally equivalent device for use with a higher ESR output capacitor, see the MAX8885 data sheet.
