STMicroelectronics AEK-POW-LDOV01J

Overview

AEK-POW-LDOV01J from STMicroelectronics is an automotive-grade evaluation board built around the L99VR01JTR linear voltage regulator IC, supporting eight selectable fixed output voltages (0.8–5.0 V), 200 mA load current, thermal warning up to 170°C, and integrated diagnostics including enable, reset, watchdog, short-circuit control, and fast discharge.

For engineers reviewing the AEK-POW-LDOV01J datasheet, AEK-POW-LDOV01J pinout, AEK-POW-LDOV01J application, or AEK-POW-LDOV01J equivalent, this board enables rapid validation of L99VR01JTR-based power supply designs for microcontroller cores, display drivers, sensor interfaces, and infotainment processors in high-temperature automotive environments.

Technical Context

The AEK-POW-LDOV01J implements a configurable LDO regulator evaluation platform with three hardware-selectable pins (SEL1–SEL3) to set one of eight output voltages, and integrates real-time diagnostics: thermal warning (TW), reset (RST), watchdog input (Wi), and enable (EN). It supports external voltage monitoring via Vo_ADC and includes fast output discharge circuitry using Q1 (BSS138Q).

Designed for AEC-Q100 Grade 0 qualification, the board uses ST's L99VR01JTR - a monolithic automotive LDO with overvoltage detection, in-short protection, and 170°C junction temperature capability - and features discrete protection components including STPS0540ZY Schottky diode, STTH102AY fast recovery diode, and SMCJ24CA transient voltage suppressor.

FAQ

Is AEK-POW-LDOV01J a standalone power supply IC?

No. AEK-POW-LDOV01J is an evaluation board, not an IC. It hosts the L99VR01JTR automotive LDO regulator and provides test points, selection jumpers, diagnostic interfaces, and protection circuitry to validate system-level behavior in real automotive power supply configurations.

What input voltage range does AEK-POW-LDOV01J support?

The board accepts 4.5 V to 40 V DC input (Vs), as defined by the L99VR01JTR's operating range. Input protection includes STTH102AY fast-recovery diode (reverse polarity) and SMCJ24CA TVS (transient suppression), enabling robust operation in 12 V and 24 V automotive systems.

How is output voltage configured on AEK-POW-LDOV01J?

Output voltage is set using three onboard DIP switches (SEL1, SEL2, SEL3) that connect to the L99VR01JTR's configuration pins. The binary combination selects one of eight factory-trimmed outputs: 0.8, 1.2, 1.5, 1.8, 2.5, 2.8, 3.3, or 5.0 V - no external resistors or firmware required.

Does AEK-POW-LDOV01J support functional safety compliance?

Yes. The underlying L99VR01JTR is designed to support ASIL-B decomposition per ISO 26262. The board exposes RST, Wi, TW, and EN signals for integration into safety-monitoring architectures, and includes dedicated test points for fault injection and diagnostic coverage validation.
