Product details
Overview
NCV86601BDT50RKG from onsemi is an automotive-grade 5.0 V fixed-output low-dropout linear regulator with 150 mA output current, ±2.0% output voltage accuracy over 4.5–40 V input, 28 µA typical quiescent current, and integrated RESET output with selectable 8 ms / 128 ms delay times. It powers microprocessors in body control modules and instrument clusters under cold-crank conditions.
For engineers reviewing the NCV86601BDT50RKG 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, stable operation with 2.2 µF ceramic output capacitor, and DT pin logic-level reset delay configuration.
Technical Context
The NCV86601BDT50RKG implements a precision bandgap reference with error amplifier feedback to maintain regulated 5.0 V output across wide input (4.5–40 V) and temperature (−40°C to +150°C) ranges. Its internal current limit (205–525 mA) and thermal shutdown circuitry protect against overload and junction overheating without foldback.
RESET functionality is implemented via a dedicated comparator monitoring VOUT with 93% nominal threshold and 2.0% hysteresis; the DT pin selects between two factory-configured delay pairs (8 ms/128 ms) by tying to GND or OUT - no external resistor required. RO provides CMOS-compatible active-low output with internal pull-up to OUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2.0% over 6–40 V input and −40°C to +125°C, enabling direct MCU core supply without trimming. |
| Quiescent Current | 28 µA typical at 13.2 V and 25°C, supporting always-on automotive modules with <100 µA standby draw. |
| Dropout Voltage | 0.30 V max at 150 mA load, allowing regulation down to VIN = 5.3 V - critical for cold-crank (6.0 V) operation. |
| Reset Threshold | 93% of nominal VOUT (4.65 V) with 2.0% hysteresis, ensuring clean power-on reset without chatter during brownout recovery. |
| Thermal Shutdown | 150°C trip point with 25°C hysteresis, preventing permanent damage during sustained overload or poor heatsinking. |
| Output Capacitance | Stable with ≥2.2 µF ceramic capacitor (low ESR), eliminating need for electrolytic or tantalum, reducing BOM cost and footprint. |
| Input Voltage Range | 4.5 V to 40 V DC, covering full automotive battery range including load dump transients up to 40 V. |
Pinout & Package
DPAK-5 (Case 175AA) package with exposed thermal tab (pin 3/tab), optimized for PCB copper area heat spreading. RJA = 66°C/W on 1 oz FR4 with 1 in² copper, RJT = 4.0°C/W to tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Supply | Accepts 4.5–40 V; requires 0.1 µF ceramic bypass to GND near IC for noise immunity and transient response. |
| 2 (RO) | Reset Output | Active-low CMOS output; internally pulled up to OUT - no external pull-up needed; sinks 10 mA min. |
| 3/Tab (GND) | Ground & Thermal Path | Primary ground return and thermal conduction path to PCB copper; must be soldered to large copper pour. |
| 4 (DT) | Delay Time Select | Logic-level input (0.8–2.0 V valid); tied to GND selects 8 ms/128 ms delay pair; sampled only when RO is low. |
| 5 (OUT) | Regulated Output | 5.0 V ±2.0% source; requires 2.2 µF ceramic capacitor to GND for stability and load transient response. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Validated for −40°C to +125°C ambient operation in automotive ECUs, meeting stringent reliability and qualification requirements. |
| Microprocessor-compatible RESET | Guaranteed 16–38 µs reaction time from VOUT undervoltage to RO assertion, enabling deterministic boot sequencing. |
| No-load stability | Maintains regulation and does not oscillate with zero output current - essential for intermittent wake-up systems. |
| Integrated protection | Thermal shutdown and short-circuit current limiting (205–525 mA) operate independently without external components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV86602BDT50RKG | Same 5.0 V output and DPAK package, but 8 ms / 32 ms RESET delay pair instead of 8 ms / 128 ms. | Suitable where shorter secondary delay is acceptable for faster system recovery after brief brownouts. | Select when system boot sequence requires quicker exit from reset after initial stabilization. |
| TLV73350PDBVR | 5.0 V fixed LDO with 300 mA output, 55 µA Iq, no RESET function, SOT-23-5 package, not AEC-Q100 qualified. | Applicable in non-automotive industrial or consumer designs where RESET is handled externally and higher current is needed. | Choose for cost-sensitive, non-automotive applications requiring higher output current and smaller footprint, but without safety-critical reset features. |
Compared with NCV86602BDT50RKG, the NCV86601BDT50RKG provides longer secondary reset delay (128 ms vs. 32 ms) for robust system initialization; versus TLV73350PDBVR, it delivers automotive qualification, integrated RESET, and lower quiescent current at the expense of output current headroom and package size.

FAQ
What is the maximum input voltage rating for the NCV86601BDT50RKG?
The NCV86601BDT50RKG has an absolute maximum input voltage of 40 V, validated per its AEC-Q100 qualification for automotive load-dump conditions. Its operating input range is 4.5 V to 40 V, ensuring reliable regulation during cold-crank (as low as 6 V) and transient overvoltage events. Exceeding 40 V may cause permanent damage.
How does the DT pin configure reset delay timing on the NCV86601BDT50RKG?
The DT pin on the NCV86601BDT50RKG selects between two factory-programmed reset delay pairs: tying DT to GND selects 8 ms (primary) / 128 ms (secondary) delay, while tying DT to OUT selects a different pair. The pin is sampled only when RO is low; changes during RO high state have no effect. No external resistor is required - logic-level drive suffices.
Is an external pull-up resistor required for the RO pin of the NCV86601BDT50RKG?
No, the NCV86601BDT50RKG includes an internal active pull-up to the OUT pin on the RO terminal, eliminating the need for an external pull-up resistor. RO delivers a CMOS-compatible active-low signal that drives low when VOUT drops below 93% of nominal (4.65 V) and returns high after the selected delay time once VOUT recovers.
What output capacitor value is required for stability with the NCV86601BDT50RKG?
The NCV86601BDT50RKG is stable with a minimum 2.2 µF ceramic output capacitor (X5R/X7R) placed directly between OUT and GND. Lower values increase power-up overshoot; larger values improve transient response but are not required. Electrolytic or tantalum capacitors are unnecessary and not recommended due to ESR sensitivity.
Does the NCV86601BDT50RKG include thermal protection, and how does it behave?
Yes, the NCV86601BDT50RKG incorporates thermal shutdown with a 150°C trip point and 25°C hysteresis. When junction temperature exceeds 150°C, the output disables and RO goes low. The device remains latched off until temperature falls below ~125°C, then resumes regulation after the configured RESET delay time - preventing thermal runaway during sustained overload.
