Taiwan Semiconductor announces the availability of the TQL8xx Family of automotive-grade, low-dropout (LDO) regulators. This high-reliability, AEC-Q101 qualified LDOs offer manufacturers a reliable alternative source for the critically important linear regulators utilized in numerous battery-driven automotive functions, including dashboard, cluster, climate control, fuel pump, and advanced driver-assistance systems (ADAS). They are also well suited for secondary supply applications where a regulated output is essential during very low-cranking voltage conditions.

Designed for stability in automotive battery-connect applications, TQL8xx LDOs maintain 2% accuracy over a wide range of input voltages and a full operating temperature range of -40 to +125C. They are offered in models with fixed outputs of 3.3V or 5. V and feature typical dropout voltages of 70-80 mV @ IO=100 mA.

The TQL8xx Family’s four package configurations offer a choice of functions: SOP-8EP package: Ignition enable pin (only). SOP-8EP-package: Enable, reset, and watchdog output; and reset threshold adjustment. TSSOP-14EP package: Enable, reset, and watchdog output; and reset threshold adjustment. TSSOP-14EP package: Enable, watchdog monitor input; watchdog output, reset threshold adjustment; and program timing adjustment.
