BD50HC0MEFJ-CE2

Datasheet Automotive 1.0 A LDO Regulator BD50HC0MEFJ-C General Description Key Specifications BD50HC0MEFJ-C is a LDO regulator with output Input Power Supply Voltage Range: 4.5 V to 8.0 V current 1.0 A. The output accuracy is 3% between Ta Output Voltage: 5.0 V = -40 C to +125 C. It has package type: HTSOP-J8 Output Current: 1.0 A (Max) which is small and good heat resistance. Over current Shutdown Current: 0 A (Typ) protection (for protecting the IC from destruction by Ambient Temperature Range Ta: -40 C to +125 C output short circuit), circuit current ON/OFF switch (for setting the circuit 0 A at shutdown mode), and thermal shutdown circuit (for protecting IC from heat destruction by over load condition) are all built in. It is Package W (Typ) x D (Typ) x H (Max) usable for ceramic capacitor and enables to improve HTSOP-J8 4.90 mm x 6.00 mm x 1.00 mm smaller set and long-life. Features (Note 1) AEC-Q100 Qualified High Accuracy Reference Voltage Circuit Built-in Over Current Protection Circuit (OCP) Built-in Thermal Shutdown Circuit (TSD) With Shutdown Switch (Note 1) Grade1 Application Power Train Body Other Automotive Products Typical Application Circuit VCC VO Components Externally Connected C CIN O Input Capacitor: 1.0 F C (Min) IN (Note 2) Output Capacitor: 1.0 F C (Min) O VO S EN S (Note 2) Electrolytic, tantalum and ceramic capacitors can be used.
