Product details
Overview
NCV8114ASN150T1G from onsemi is a 300 mA automotive-grade CMOS low-dropout linear regulator delivering 1.5 V output with ±1% accuracy at room temperature, 135 mV typical dropout at full load, and 75 dB PSRR at 1 kHz - designed for noise-sensitive, space-constrained battery-powered systems including parking camera modules and infotainment head units.
For engineers reviewing the NCV8114ASN150T1G datasheet, pinout, applications, or equivalent options, key selection considerations include its AEC-Q100 qualification, active output discharge function (enabled in this variant), dynamic quiescent current adjustment (50 µA typ. at no-load), thermal shutdown (160°C), and stability with only 1 µF ceramic output capacitor.
Technical Context
The NCV8114ASN150T1G integrates a PMOS pass transistor with inherent reverse-current protection awareness, an internal bandgap reference, and enable-controlled active discharge via a 100 Ω pull-down path. Its dynamic IQ adjustment maintains ultra-low standby current (0.1 µA typ.) while supporting fast transient response under 1 mA to 300 mA load steps.
It operates across −40°C to +125°C ambient, features built-in current limiting (600 mA typ.), thermal shutdown with 20°C hysteresis, and requires no minimum ESR on the output capacitor - unlike many LDOs, it remains stable with 0.22 µF minimum effective COUT, accommodating small-footprint 0402 MLCCs under DC bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V - eliminates external feedback network; supports logic rails for automotive microcontrollers and image sensors. |
| Max Output Current | 300 mA continuous - sufficient for powering single-core SoCs, camera ISP blocks, or Bluetooth/Wi-Fi co-processors. |
| Dropout Voltage | 135 mV typical at 300 mA - enables operation down to VIN = 1.635 V, critical for brown-out resilience in 1.8 V/2.5 V system domains. |
| Quiescent Current | 50 µA typical at no-load - extends battery life in always-on parking camera modules during vehicle sleep mode. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Accuracy | ±1% at 25°C - ensures reliable voltage margining for 1.5 V DDR I/O or LPDDR interfaces without derating. |
| Enable Threshold | 0.9 V high / 0.4 V low - compatible with standard GPIOs and supports direct tie-to-IN if enable functionality is unused. |
Pinout & Package
NCV8114ASN150T1G is housed in a Pb-free TSOP-5 (Case 483) package measuring 3.00 × 1.50 × 0.95 mm with 0.95 mm pitch. The exposed pad is internally connected to GND and must be soldered to a PCB ground plane for optimal thermal performance (RJA = 259.9°C/W on 1 oz FR4 with 645 mm² copper).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input power supply connection | Accepts 1.7–5.5 V; requires ≥1 µF ceramic capacitor close to pin to suppress high-frequency noise and limit inrush current. |
| 2 - GND | Power ground reference | Primary return path; must be low-impedance; ties to exposed thermal pad for junction cooling. |
| 3 - EN | Enable control input | Active-high logic: >0.9 V enables regulation; <0.4 V disables output and activates 100 Ω active discharge to GND. |
| 4 - N/C | No-connect terminal | Not electrically bonded; may be tied to GND to improve thermal dissipation without affecting function. |
| 5 - OUT | Regulated output voltage | Delivers 1.5 V ±1%; requires ≥1 µF X5R/X7R ceramic capacitor placed adjacent to pin for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Rated for automotive applications (Grade 1: −40°C to +125°C), with PPAP capability and unique site/control change requirements per NCV prefix. |
| Active output discharge | Integrated 100 Ω NMOS discharge path pulls OUT to GND within microseconds upon EN deactivation - prevents floating rail issues in multi-rail systems. |
| Ultra-low IQ | 50 µA typical quiescent current at no-load, dropping to 0.1 µA in shutdown - minimizes parasitic drain in battery-backed systems. |
| Stable with minimal capacitance | Guaranteed stability with 1 µF ceramic output capacitor (0.22 µF min. effective), enabling use of compact 0402 MLCCs even under DC bias. |
| Robust protection suite | Includes thermal shutdown (160°C trip, 140°C reset), current limit (600 mA typ.), and short-circuit immunity with unlimited duration tolerance. |
Applications
| Parking Camera Module | Automotive Infotainment Head Unit |
|---|---|
Use Scenario: Powering image sensor and ISP in rear-view camera systems that remain partially active during vehicle sleep mode. IC Role / Device Role / Timing Role: Primary 1.5 V LDO supplying sensor analog core and digital interface, with active discharge ensuring clean power-down sequencing.

IC Role / Device Role / Timing Role: Precision 1.5 V rail generator for high-speed SerDes PHYs requiring tight voltage tolerance and low jitter injection. Use Value: ±1% output accuracy over −40°C to +125°C avoids timing margin loss; low dropout preserves headroom for 1.8 V input sources. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8114ASN150T2G | Same electrical specs and TSOP-5 package; differs only in tape-and-reel quantity (10,000 pcs vs. 3,000 pcs) and date-code marking format. | No functional difference; identical use in automotive PCBs and qualification status. | Select when higher reel volume aligns with production planning or logistics requirements. |
| TLD1114-15V | 150 mA rated, fixed 1.5 V, SOIC-8 package; lacks active discharge and AEC-Q100 Grade 1 rating; PSRR = 65 dB @ 1 kHz. | Suitable for non-automotive industrial or consumer applications where lower current and relaxed qualification suffice. | Choose only for cost-sensitive, non-automotive designs with ≤150 mA load and no active discharge requirement. |
Compared with NCV8114ASN150T1G, NCV8114ASN150T2G offers identical performance in larger reels, while TLD1114-15V trades current capability, automotive qualification, and active discharge for lower cost and wider package availability - making it unsuitable for safety-critical or high-transient automotive loads.

FAQ
What is the output voltage tolerance of the NCV8114ASN150T1G over temperature?
The NCV8114ASN150T1G maintains ±1% output voltage accuracy at room temperature (25°C). Over the full operating junction temperature range (−40°C to +125°C), output voltage deviation is specified as ±50 mV for 1.5 V output - equivalent to ±3.3% full-scale error, verified by characterization and guaranteed by design.
Does the NCV8114ASN150T1G include active output discharge, and how does it behave?
Yes, the NCV8114ASN150T1G includes active output discharge. When the EN pin voltage falls below 0.4 V, the device disables regulation and activates an internal 100 Ω NMOS discharge path between OUT and GND, pulling the output voltage to ground within tens of microseconds - preventing unintended back-powering of upstream circuitry.
What is the minimum output capacitor required for stability with the NCV8114ASN150T1G?
The NCV8114ASN150T1G is stable with a minimum effective output capacitance of 0.22 µF. It is recommended to use a 1 µF X5R or X7R ceramic capacitor (e.g., 0402 or 0603) placed adjacent to the OUT pin. This value accounts for capacitance loss due to DC bias, temperature, and aging - ensuring stability across all operating conditions.
Can the NCV8114ASN150T1G operate from a 1.8 V input supply?
Yes, the NCV8114ASN150T1G supports input voltages from 1.7 V to 5.5 V. With a 1.5 V output, the minimum required input is 1.635 V (1.5 V + 135 mV dropout). Therefore, a 1.8 V input provides 165 mV of headroom - sufficient for stable regulation even under worst-case dropout and load conditions.
Is the NCV8114ASN150T1G pin-compatible with other variants in the NCV8114 family?
Yes, all NCV8114 variants - including NCV8114ASN150T1G, NCV8114ASN330T1G, and NCV8114BSN150T1G - share identical TSOP-5 (Case 483) pinout and footprint. The only differences are output voltage, presence/absence of active discharge, and marking code - enabling drop-in replacement during design iteration or voltage optimization.
