Description
The TC1303/TC1304 combines a 500 mA synchronous buck regulator and 300 mA Low-Dropout Regulator (LDO) with a power-good monitor to provide a highly integrated solution for devices that require multiple supply voltages..
Features
- Dual-Output Regulator (500 mA Buck Regulator and 300 mA Low-Dropout Regulator).
- Power-Good Output with 300 ms Delay www. DataSheet4U. com.
- Total Device Quiescent Current = 65 µA, Typ.
- Independent Shutdown for Buck and LDO Outputs (TC1303).
- Both Outputs Internally Compensated.
- Synchronous Buck Regulator: - Over 90% Typical Efficiency - 2.0 MHz Fixed-Frequency PWM (Heavy Load) - Low Output Noise - Automatic PWM to PFM mode transition - Adjustab.
