The TPS7B69xx device is a low-dropout linear regulator that operates at up to 40-V VI. With only
15-μA (typical) quiescent current at light load, the device is applicable for standby microcontrol-unit systems, especially for always-on applications like e-meters, fire alarms, and smoke detectors.
The devices have integrated short-circuit and overcurrent protection. The TPS7B69xx device operates over a –40°C to 105°C temperature range.
