STMicroelectronics L99VR01STR | Demoboard AEK-POW-LDOV01S
Getting started with the AEK-POW-LDOV01J and AEK-POW-LDOV01S automotive-grade LDOs with configurable output voltage
Overview
| Topology | Other Topology |
| IC revision | 1 |
Description
The AEK-POW-LDOV01J and AEK-POW-LDOV01S evaluation boards host, respectively, the L99VR01JTR and L99VR01STR voltage regulator ICs, which are two different versions of the L99VR01.The L99VR01 is a DC-DC voltage regulator designed for automotive applications (AEC-Q100 qualified). It can deliver up to 200 mA of load current and consumes around 1 μA when the regulator is disabled.The operating input voltage is between 2.15 and 28 V, while a fixed selectable output voltage (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V,2.8 V, 3.3 V, or 5 V) is configurable.
Features
- AEC-Q100 qualified
- Operating DC power supply voltage range from 2.15 V to 28 V
- Battery and post regulation operating modes are allowed
- Low dropout voltage
- Low quiescent current consumption
- User-selectable output voltage (0.8 V; 1.2 V; 1.5 V; 1.8 V; 2.5 V; 2.8 V; 3.3 V or 5 V)
- Output voltage precision ±2%
- Enable input for enabling/disabling the voltage regulator
- Output voltage monitoring with reset output
- Negligible ESR effect on output voltage stability for load capacitor
- Programmable autonomous watchdog through external capacitor (L99VR01J only)
- Under voltage lockout UVLO
- Fast output discharge
- Thermal shutdown and short-circuit current limitation
- Advanced thermal warning and output overvoltage diagnostic (L99VR01J only)
- Programmable short-circuit output current (L99VR01J only)
- Wide operating temperature range (TJ = -40°C to 175°C L99VR01J only)
- Limited documentation available for customers that need support when dealing with ASIL requirements as per ISO 26262
Typical applications
- Automotive-grade LDO
