3.3v / 5v Dual-voltage Regulator With Watchdog Timer - Toshiba Semiconductor

Designed specifically TA8044AF for use in 3.3V microcomputers, this IC contains two constant-voltage power supplies for 3.3V and 5V uses and various system reset functions. This IC's Power Supply Output 1 provides an output voltage of 3.4V and contains an output Transistor capable of producing 10mA of output current. With an external boost Transistor connected, this IC CAN supply a large output current. A 150mA current limiter is included. Power Supply Output 2 provides an output voltage of 5.0V which CAN be turned on or off from the EN pin. This output uses an external output Transistor Any desired current limiter value CAN be set using an external adjusting resistor. For a system reset, it has a low-voltage monitor / power-on reset / watchdog Timer at Power Supply Output 2. By Toshiba Semiconductor
