Taiwan Semiconductor Offers New Source for Critical Automotive-Grade Low-Dropout Linear Regulators

­Taiwan Semiconductor announces the availability of the TQL8xx Family of automotive-grade, low-dropout (LDO) regulators. These 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:

1. SOP-8EP package: Ignition enable pin (only)
2. SOP-8EP-package: Enable, reset and watchdog output; and reset threshold adjustment
3. TSSOP-14EP package: Enable, reset and watchdog output; and reset threshold adjustment
4. TSSOP-14EP package: Enable, watchdog monitor input; watchdog output, reset threshold adjustment; and program timing adjustment

“These reliable, in-house-manufactured AEC-qualified LDO devices provide a viable alternate source for high-demand devices used in myriad automotive battery circuit applications,” said Vice President, TSC Products, Sam Wang. “They also provide a high-performance option in industrial and high-reliability applications.”

Design resources include comprehensive datasheets and spice models for each component in the series.
