Product details
Overview
NCV86602BDT33RKG from onsemi is an AEC-Q100 qualified automotive-grade linear voltage regulator delivering a fixed 3.3 V output at up to 150 mA, with ±2.0% output accuracy across 4.5–40 V input and −40°C to +150°C junction temperature. It features integrated RESET output with selectable delay times (8 ms/32 ms), ultra-low 28 µA typical quiescent current, and thermal shutdown protection - designed for microprocessor power in body control modules and instrument clusters.
For engineers reviewing the NCV86602BDT33RKG datasheet, pinout, applications, or equivalent options, this page provides verified technical context, package-validated pin functions, automotive-grade reliability data, and real-world design implications for low-Iq power sequencing in harsh-environment ECUs.
Technical Context
The NCV86602BDT33RKG implements a precision bandgap reference with dual error amplifiers and internal timing circuitry to generate a stable 3.3 V output under no-load and full-load conditions. Its RESET function monitors VOUT with 93% nominal threshold and 2.0% hysteresis, asserting low when output drops >7% - independent of input voltage down to VOUT = 1.0 V.
Delay time selection (8 ms / 32 ms) is controlled by the DT pin logic state (GND or OUT), sampled only during RESET assertion. Thermal shutdown activates at 175°C typical with 25°C hysteresis, disabling output and pulling RO low until die temperature falls below 150°C - ensuring robust operation in engine-bay environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2.0% over 4.5–40 V input, −40°C to +125°C - ensures reliable MCU core logic supply despite battery transients. |
| Quiescent Current | 28 µA typical at 13.2 V, 25°C - enables <10 µA system standby current in always-on ECU nodes. |
| Output Current | 150 mA continuous - sufficient for low-power MCUs, CAN transceivers, and sensor interfaces without external pass devices. |
| RESET Delay Times | 8 ms (DT = GND) / 32 ms (DT = OUT) - supports fast-boot and fail-safe boot sequencing per ISO 26262 ASIL-B requirements. |
| Dropout Voltage | 0.30 V max at 150 mA - allows operation down to 3.6 V input, critical during cold-crank (6 V min). |
| Thermal Shutdown | 175°C activation with 25°C hysteresis - prevents latch-up in enclosed enclosures with limited airflow. |
| PSRR | 60 dB at 100 Hz - suppresses alternator ripple and switching noise before sensitive analog peripherals. |
Pinout & Package
DPAK-5 (Case 175AA) package with exposed thermal tab (pin 3/tab = GND). Thermally optimized for PCB copper area ≥645 mm²; RJA = 66°C/W typical on 1 oz FR4 with 1 in² copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply | Accepts 4.5–40 V DC; requires 0.1 µF ceramic bypass capacitor directly to GND for stability and transient response. |
| 2 (RO) | Reset output | CMOS-compatible open-drain output; actively pulled high to VOUT; asserts low on undervoltage - no external pull-up needed. |
| 3 & Tab (GND) | Ground reference | Primary ground return and thermal path; tab must be soldered to large copper pour for thermal management. |
| 4 (DT) | Delay time select | Logic-controlled input: tie to GND for 8 ms delay, to OUT for 32 ms delay; sampled only during RESET assertion. |
| 5 (OUT) | Regulated output | 3.3 V source; requires 2.2 µF low-ESR ceramic capacitor to GND; stable with capacitors ≥2.2 µF and ESR ≤100 mΩ. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation - meets automotive ECU reliability and lifetime requirements. |
| No-load stability | Maintains regulation with zero output load - eliminates need for dummy loads in sleep-mode applications. |
| Integrated protection | Thermal shutdown + short-circuit current limiting (205–525 mA) - prevents damage during wiring faults or output shorts. |
| Pb-free DPAK package | RoHS-compliant, MSL Level 1 - supports lead-free reflow without moisture sensitivity concerns. |
| Low dropout at full load | 0.30 V max dropout at 150 mA - enables use in 5 V systems with minimal headroom loss. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-Iq automotive LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV86602BDT33R2G | SOIC-8 fused package (RJA = 104°C/W); same electrical specs but lower thermal performance. | Suitable for lower-power (<100 mA), space-constrained PCBs where thermal mass is adequate. | Select when board layout lacks thermal copper area for DPAK; derate output current to 100 mA at 105°C ambient. |
| TLV73333PDBVR | 300 mA output, 45 µA Iq, non-automotive grade; no RESET or delay select; smaller SOT-23-5 package. | Applicable for cost-sensitive consumer or industrial designs without AEC-Q100 or RESET requirements. | Choose only for non-automotive use cases; lacks automotive qualification, thermal shutdown, and RESET functionality. |
Compared with NCV86602BDT33RKG, the SOIC-8 alternative trades thermal capability for footprint reduction, while the TLV73333PDBVR sacrifices automotive reliability and supervision features for higher current and smaller size - neither offers drop-in replacement without redesign.

FAQ
What is the maximum input voltage the NCV86602BDT33RKG can withstand?
The NCV86602BDT33RKG supports an absolute maximum input voltage of 40 V, with operating range from 4.5 V to 40 V. This enables robust operation during automotive load-dump events (up to 35 V per ISO 7637-2) and cold-crank conditions down to 4.5 V - critical for engine-bay ECUs. Exceeding 40 V risks permanent damage per absolute maximum ratings.
Does the NCV86602BDT33RKG require an external pull-up resistor on the RO pin?
No, the NCV86602BDT33RKG includes an internal active pull-up to VOUT on the RO pin, eliminating the need for an external resistor. The RESET output is CMOS-compatible and drives low during undervoltage events; it remains high during normal regulation. This simplifies PCB layout and reduces BOM count in space-constrained automotive modules.
How does the DT pin configure the RESET delay time for the NCV86602BDT33RKG?
The DT pin on the NCV86602BDT33RKG selects between two factory-configured RESET delay times: 8 ms when tied to GND, and 32 ms when tied to OUT. The selection is sampled only when RO is low; changes during normal operation have no effect. This enables flexible boot timing without firmware configuration - essential for ASIL-B compliant systems.
What thermal management is required for the NCV86602BDT33RKG at full 150 mA load?
At 150 mA and 13.2 V input, the NCV86602BDT33RKG dissipates ~150 mW. With RJA = 66°C/W, junction temperature rise is ~10°C above ambient - well within the −40°C to +150°C rating. Use ≥645 mm² of 1 oz copper connected to the exposed tab; avoid thermal isolation. No heatsink is needed for ambient ≤105°C.
Is the NCV86602BDT33RKG compatible with ceramic output capacitors?
Yes, the NCV86602BDT33RKG is optimized for ceramic capacitors: 2.2 µF minimum value with ESR ≤100 mΩ ensures stability across temperature and load. The device remains stable with capacitors up to 100 µF and ESR as low as 1 mΩ - enabling compact, high-reliability filtering without tantalum or electrolytic components in automotive designs.
