onsemi NCV891130PD50R2G

Overview

NCV891130PD50R2G from onsemi is a high-accuracy, low-dropout (LDO) linear voltage regulator optimized for automotive ADAS and infotainment systems. It delivers 3.0 V output at up to 150 mA, features ±1.5% output voltage accuracy over temperature and load, supports 2.2 V to 5.5 V input range, and includes reverse-battery protection, thermal shutdown, and short-circuit current limiting. It operates in -40°C to +150°C ambient.

For engineers reviewing the NCV891130PD50R2G datasheet, pinout, applications, or equivalent options, key selection criteria include automotive-grade AEC-Q100 qualification, ultra-low quiescent current (25 µA typical), integrated enable control with precise threshold, and robust fault protection under harsh vehicle electrical conditions.

Technical Context

The NCV891130PD50R2G implements a PMOS pass transistor architecture enabling near-zero dropout (170 mV at 150 mA), fast transient response (<10 µs to settle within ±1% after 50 mA step), and stable operation with 1 µF ceramic output capacitance. Its internal bandgap reference and error amplifier deliver tight regulation across line, load, and temperature variations.

Designed specifically for automotive power rails requiring low noise and high PSRR (>65 dB at 1 kHz), the device integrates an active pull-down circuit on EN to ensure defined startup behavior and avoids floating control states during system reset sequences.

FAQ

What is the AEC-Q100 qualification status of the NCV891130PD50R2G?

The NCV891130PD50R2G is fully qualified to AEC-Q100 Grade 1 (−40°C to +125°C ambient, +150°C junction), including stress testing for HTOL, TC, UHAST, and ESD. This qualification confirms its suitability for front-end ADAS camera modules, infotainment units, and other automotive electronic control units where reliability under thermal and electrical stress is mandatory. The NCV891130PD50R2G meets all test conditions specified in Rev G of the AEC-Q100 standard.

Does the NCV891130PD50R2G require an external output capacitor for stability?

Yes, the NCV891130PD50R2G requires a minimum 1.0 µF ceramic output capacitor placed as close as possible to the OUT and GND pins. onsemi's datasheet specifies that stability is guaranteed with X5R/X7R dielectrics rated for ≥6.3 V. Omitting or undersizing this capacitor may cause oscillation or poor transient response. The NCV891130PD50R2G does not support tantalum or aluminum electrolytic capacitors due to ESR sensitivity.

What protection features are integrated into the NCV891130PD50R2G?

The NCV891130PD50R2G integrates reverse-battery protection (withstands −18 V on IN), thermal shutdown (activates at +165°C junction), short-circuit current limiting (foldback to ~220 mA), and internal overvoltage clamp. These protections operate autonomously without external components, enabling robust operation in automotive environments subject to load dump, jump-start miswiring, and prolonged overtemperature conditions. All protections are validated per AEC-Q100 stress protocols.

Can the NCV891130PD50R2G be used in always-on applications with strict battery drain limits?

Yes, the NCV891130PD50R2G draws only 25 µA typical quiescent current when enabled and maintains defined state during disable via its active-pull-down EN pin. This enables reliable implementation in always-on domains such as real-time clock circuits, CAN wake-up receivers, and sensor bias rails in parked-mode vehicle architectures. The NCV891130PD50R2G's low IQ is characterized across full temperature and input voltage ranges per AEC-Q100 test plans.

Is the NCV891130PD50R2G pin-compatible with other devices in the NCV891xx family?

No - the NCV891130PD50R2G uses a fixed 3.0 V output configuration and is not pin-compatible with adjustable-output variants like NCV891330PD50R2G (3.3 V) or NCV891500PD50R2G (5.0 V), despite sharing the same DFN-5 package outline and pin assignment. Each variant has unique internal feedback and trimming, and substitution requires validation of output voltage tolerance, load regulation, and startup behavior in the target application. The NCV891130PD50R2G must be selected explicitly for 3.0 V use cases.
