onsemi NCV86601D50R2G

Overview

NCV86601D50R2G from onsemi is a precision automotive-grade low-dropout linear regulator delivering fixed 5.0 V output at up to 150 mA, with ±2.0% output voltage accuracy across 4.5–40 V input and −40°C to +150°C junction temperature. It integrates RESET output with 8 ms delay (DT = GND) and features ultra-low 28 µA typical quiescent current-ideal for always-on body control modules.

For engineers reviewing the NCV86601D50R2G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 qualification, thermal shutdown (150°C trip), dropout voltage ≤0.30 V at 150 mA, CMOS-compatible RESET assertion at 93% VOUT, and SOIC-8 fused package compatibility with Pb-free reflow.

Technical Context

The NCV86601D50R2G implements a bandgap-referenced error amplifier driving a PNP pass transistor, enabling stable regulation under no-load conditions and flat quiescent current vs. load. Its RESET circuit samples VOUT continuously and asserts RO low when output drops >7% below nominal, with hysteresis of 2.0% VOUT.

Delay time selection is implemented via DT pin logic threshold (0.8 V low / 2 V high), sampled only during RESET assertion; DT tied to GND selects 8 ms delay, while DT tied to OUT selects 128 ms. Thermal shutdown uses a dedicated die-temperature sensor with 25°C hysteresis to prevent latch-up.

FAQ

What is the RESET delay time configuration for NCV86601D50R2G?

The NCV86601D50R2G is configured for 8 ms RESET delay when the DT pin is connected to GND, and 128 ms when DT is connected to OUT. The DT pin is sampled only during RESET assertion, so changes to DT while RO is high have no effect. This dual-delay capability allows flexible system-level timing without external timers.

Does NCV86601D50R2G require an external pull-up resistor on the RO pin?

No, NCV86601D50R2G does not require an external pull-up resistor on the RO pin. It features an internal active pull-up to the OUT pin, ensuring reliable CMOS-compatible logic levels (V_RL ≤ 0.4 V, V_RH ≥ V_OUT − 0.2 V) without additional components - reducing BOM count and layout complexity.

What is the maximum input voltage rating for NCV86601D50R2G?

The absolute maximum input voltage for NCV86601D50R2G is 40 V, with recommended operating range from 4.5 V to 40 V. This wide input range supports direct connection to automotive battery rails, including transient spikes up to 40 V per ISO 7637-2, while maintaining regulated 5.0 V output.

Can NCV86601D50R2G operate with zero load current?

Yes, NCV86601D50R2G is explicitly designed for stable operation under no-load conditions. Its architecture maintains regulation and low quiescent current (28 µA typical) even with I_OUT = 0 mA, eliminating the need for minimum load resistors - essential for ultra-low-power automotive sleep modes.

What thermal protection features does NCV86601D50R2G include?

NCV86601D50R2G includes thermal shutdown with a 150°C trip point and 25°C hysteresis, plus short-circuit current limiting (205 mA minimum). When thermal shutdown activates, OUT is disabled and RO goes low; the device remains latched off until die temperature falls below 125°C, then resumes regulation after the configured RESET delay time.
