Single-Output LDO Regulator
Ultra Low Quiescent Current LDO
Regulator
BD7xxL5FP-C
●General
Description
The BD7xxL5FP-C are low quiescent regulators
featuring 50V absolute maximum voltage, and output
voltage accuracy of ±2%, 500mA output current and 6μA
(Typ.) current consumption. There regulators are
therefore ideal for applications requiring a direct
connection to the battery and a low current consumption.
Ceramic capacitors can be used for compensation of the
output capacitor phase. Furthermore, these ICs 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.
●Features
Ultra low quiescent current: 6.0μA (Typ.)
Output current capability: 500mA
Output voltage: 3.3 V or 5.0 V(Typ.)
High output voltage accuracy: ±2%
Low saturation voltage by using PMOS output
transistor.
Integrated overcurrent protection to protect the IC
from damage caused by output short-circuiting.
Integrated thermal shutdown to protect the IC from
overheating at overload conditions.
Low ESR ceramic capacitor can be used as output
capacitor.
