DESCRIPTION
The UTC LR9107 is a CMOS-based low dropout regulator with high output voltage accuracy, low dropout, high PSRR and low quiescent current.
The UTC LR9107 includes a voltage reference unit, an error amplifier, current limit circuit, resistors for setting output voltage, and a chip enable circuit. With its low power consumption, excellent line and load transient response, the UTC LR9107 is well suited for low power handheld communication equipment.
Since the output capacitor and noise bypass capacitor are able to be reduced, high density mounting on boards are possible.
