Description
The MAX8862 low-cost, low-dropout, dual linear voltage regulator is ideal for battery-powered and portable applications. The regulators have independent supply inputs and provide 250mA and 100mA, respectively, with a full-load dropout voltage of 160mV. Both regulators use P-channel MOSFET pass transistors and maintain low quiescent current independent of load current. In dropout, the MOSFET does not suffer from excessive base currents, as do saturated PNP transistors.

The MAX8862 output voltage is preset to 4.95V (L), 3.175V (T), or 2.85V (R). This device employs Dual Mode™ operation, allowing user-adjustable outputs from +2V to +11V with external resistors. The input supply-voltage range is 2.5V to 11.5V. Other features include independent shutdown, power-good indicator, short-circuit and reverse-battery protection, and thermal shutdown.

The MAX8862's regulators are ideal power supplies for the radio and the microcontroller (µC) used in digital, cordless, and PCS phones. The main regulator is optimized for superior transient and dynamic response, while the secondary regulator exhibits low-output, wideband noise.

The MAX8862 comes in a 16-pin SO package with a lead frame that uses multiple GND pins as a heat sink for additional thermal dissipation.
