Power Management ICs for Automotive Body Control
LDO
Regulator
BD3650FP-M
No.10039EAT08
●Description
The BD3650FP-M is low-saturation regulator.
This IC has a built-in over-current protection circuit that prevents the destruction of the IC due to output short circuits and a
thermal shutdown circuit that protects the IC from thermal damage due to overloading.
●Features
1) Output Current: 0.3A
2) High Output Voltage Precision :
±2%
3) Low saturation with PDMOS output
4) Built-in over-current protection circuit that prevents the destruction of the IC due to output short circuits
5) Built-in thermal shutdown circuit for protecting the IC from thermal damage due to overloading
6) Low ESR Capacitor
7) TO252-3 packaging
●Applications
Onboard devices (vehicle equipment, car stereos, satellite navigation systems, etc.)
