Product details
Overview
NCV33269DT-5.0G from onsemi is an automotive-grade, fixed-output 5.0 V low-dropout linear voltage regulator in DPAK (TO-252) package, delivering ≥800 mA output current with 1.0 V dropout at 500 mA and ±1.0% output voltage tolerance over temperature. It integrates thermal shutdown and short-circuit protection, and is AEC-Q100 qualified for under-hood power rail regulation in engine control units and body electronics.
For engineers reviewing the NCV33269DT-5.0G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, validated DPAK terminal mapping, automotive thermal performance data, and direct-fit alternatives for production design-in and BOM rationalization.
Technical Context
The NCV33269DT-5.0G uses a composite PNP–NPN pass transistor architecture to achieve 1.0 V dropout at 500 mA while maintaining stability with ≥10 µF output capacitance. Its internal reference is trimmed to 1.25 V (±1.2%) and supports line/load/temperature regulation within ±1.0% across −40°C to +125°C ambient.
Thermal protection activates at ~170°C junction temperature without hysteresis, disabling output until cooldown. Input voltage range is 6.5 V to 20 V (ensuring ≥1.5 V headroom above 5.0 V output), and ripple rejection is 55 dB at 120 Hz with 10 µF tantalum output capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±1.0% (guaranteed over −40°C to +125°C, 10 mA–800 mA load) |
| Dropout Voltage | 1.0 V max at 500 mA (enables operation with Vin as low as 6.0 V; 1.25 V max at 800 mA) |
| Output Current | ≥800 mA continuous (internally current-limited; derates with thermal rise) |
| Ripple Rejection | 55 dB min at 120 Hz (rejects input supply noise critical for ECU sensor rails) |
| Quiescent Current | 8.0 mA max (low no-load consumption for always-on vehicle modules) |
| Thermal Shutdown | Activates at ~170°C junction (non-hysteretic; protects against sustained overload or poor heatsinking) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8664CDT50RKG | Lower quiescent current (25 µA vs. 8 mA), 150 mA output, same DPAK package | Suitable only for ultra-low-power always-on nodes (e.g., wake-up circuits), not high-current loads | Select when standby current dominates design priority; not a drop-in replacement for 800 mA loads |
| TLV73350PDBVR | Higher PSRR (65 dB @ 1 kHz), 300 mA output, SOT-23-5 package, no thermal shutdown hysteresis | Targeted at portable infotainment subsystems; lacks AEC-Q100 qualification and automotive temp range | Use in non-automotive consumer modules where size and noise rejection outweigh qualification needs |
Compared with NCV33269DT-5.0G, NCV8664CDT50RKG trades output current for nanoamp quiescent draw, while TLV73350PDBVR offers superior AC performance in a smaller footprint but sacrifices automotive reliability and thermal robustness.

FAQ
What is the maximum input voltage for NCV33269DT-5.0G?
The absolute maximum input voltage for NCV33269DT-5.0G is 20 V, as specified in the Maximum Ratings table. Operation above this voltage risks permanent device damage. For reliable 5.0 V regulation, input should remain between 6.5 V (to maintain dropout margin) and 20 V, with recommended derating above 15 V in high-temperature environments.
Does NCV33269DT-5.0G require an external output capacitor, and what type is recommended?
Yes, NCV33269DT-5.0G requires a minimum 10 µF output capacitor for stability. Solid tantalum capacitors are preferred due to stable ESR over temperature; aluminum electrolytic types may cause oscillation at low temperatures. Ceramic capacitors are not recommended unless explicitly validated, as their near-zero ESR can destabilize the control loop.
Is NCV33269DT-5.0G pin-compatible with MC33269DT-5.0G?
Yes, NCV33269DT-5.0G and MC33269DT-5.0G share identical DPAK pinout (Pin 1 = GND, Pin 2 = VOUT, Pin 3 = VIN) and electrical specifications. The NCV prefix denotes automotive qualification (AEC-Q100 Grade 1), while MC33269DT-5.0G is for commercial/industrial use - both are mechanically and electrically interchangeable in layout.
What thermal performance can be expected from NCV33269DT-5.0G in a standard 2-layer PCB?
In a standard 2-layer PCB with 2 oz. copper and a 25 mm² thermal pad connected to Pin 2, NCV33269DT-5.0G achieves θJA ≈ 92°C/W. At 800 mA output and 1.25 V dropout (1.0 W dissipation), junction temperature rise is ~92°C above ambient - requiring ambient ≤ 58°C for safe operation at 150°C max TJ.
How does the thermal shutdown behavior of NCV33269DT-5.0G affect system operation?
NCV33269DT-5.0G features non-hysteretic thermal shutdown that disables output at ~170°C junction temperature. If cooling is insufficient, the device cycles on/off, causing visible output oscillation. This is a fail-safe mechanism - not a regulated thermal management feature - so proper heatsinking or power derating is mandatory for continuous 800 mA operation.
