稳压ic ldo utc lr3xxyyb

150ma 2ch ldo regulator

description
the utc lr3xxyyb are cmos voltage regulator ics that have high output voltage accuracy, low dropout, low supply current, and high ripple rejection. every voltage regulator ic of utc lr3xxyyb series consists of an error amplifier, a voltage reference unit, a current limit circuit, resistors for setting output voltage, and a chip enable circuit.
due to built-in transistor with low on resistance and a chip enable function these ics perform with low dropout voltage prolongs the battery life of each system. the load transient response and line transient response of the utc lr3xxyyb series are excellent, sothese ics are suitable for hand-held communication equipmentpower supply.
