描述
BD433S5WFP2-C is low quiescent regulators featuring 45V absolute maximum voltage, and output voltage accuracy of ±2% (3.3V or 5V: Typ), 500mA output current and 38µA (Typ) current consumption. This regulator is therefore ideal for applications requiring a direct connection to the battery and a low current consumption. A logical “HIGH” at the CTL enables the device and “LOW” at the CTL disables the device. Ceramic capacitors can be used for compensation of the output capacitor phase. Furthermore, this IC also feature overcurrent protection to protect the device from damage caused by short-circuiting and an integrated thermal shutdown to protect the device from overheating at overload conditions.

Control Output Voltage ON/OFF

Internal Power Supply

Thermal Shutdown Protection

Reference Voltage

Power Supply for Internal Circuit

To protect the device from overheating.

If the chip temperature ( Tj ) reaches ca. 175 °C ( Typ ),

the output is turned off.

VREF

Generate the Reference Voltage

Drive the Output MOS FET

DRIVER

OCP

Over Current Protection

To protect the device from damage caused by over current.

If the output current reaches ca. 900 mA ( Typ ),

the output is turned off.

(Note 1) Applicable for product with Enable Input.
