Low-Cost, Low-Dropout, Dual Linear Regulator
_______________General 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 regula-
tors use P-channel MOSFET pass transistors and main-
tain 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 ther-
mal 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 opti-
mized for superior transient and dynamic response,
