Product details
Overview
NCV8114ASN170T1G from onsemi is a 300 mA automotive-grade CMOS low-dropout linear regulator with fixed 1.7 V output, ±1% accuracy at room temperature, 135 mV typical dropout at full load, and dynamic quiescent current adjustment enabling 50 µA typical IQ. It delivers stable power to noise-sensitive modules in parking camera systems and infotainment head units.
For engineers reviewing the NCV8114ASN170T1G datasheet, pinout, applications, or equivalent options, key selection factors include its AEC-Q100 qualification, TSOP-5 package thermal performance (RJA = 259.9 °C/W), active output discharge function (enabled in ASN variant), PSRR of 75 dB at 1 kHz, and compatibility with 1 µF ceramic output capacitors.
Technical Context
The NCV8114ASN170T1G integrates a PMOS pass transistor with internal bandgap reference, thermal shutdown (160 °C trip), current limit (600 mA typ), and enable-controlled active discharge (100 Ω pull-down). Its dynamic IQ adjustment maintains ultra-low 50 µA quiescent current at no-load while scaling under load to sustain regulation.
It operates across 1.7 V to 5.5 V input, supports −40 °C to +125 °C ambient, and achieves ±1% output accuracy over temperature. The TSOP-5 package includes an exposed pad tied to GND for thermal relief, and the EN pin features 0.9 V turn-on / 0.4 V turn-off thresholds with 300 nA internal pull-down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.7 V - precisely regulated rail for low-voltage logic, image sensors, or RF front-end biasing. |
| Max Output Current | 300 mA continuous - sufficient for single-camera module or Bluetooth SoC core supply. |
| Dropout Voltage | 170 mV typical at 300 mA - enables operation from 1.87 V input, critical for Li-ion battery brownout conditions. |
| Quiescent Current | 50 µA typical at no-load - extends battery life in always-on parking camera wake-up circuits. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters in compact infotainment PCBs. |
| Accuracy | ±1% at 25 °C - ensures reliable operation of 1.7 V I/O interfaces without margining overhead. |
| Enable Threshold | 0.9 V high / 0.4 V low - compatible with standard GPIOs and supports clean sequencing in multi-rail systems. |
| Package | TSOP-5 (Case 483) - 3.0 × 1.5 × 0.95 mm surface-mount footprint with exposed thermal pad. |
Pinout & Package
NCV8114ASN170T1G is housed in a 5-pin TSOP-5 package (Case 483) with exposed thermal pad connected to GND. Pin 4 is not connected but may be grounded to improve thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Input voltage supply | Accepts 1.7–5.5 V; requires ≥1 µF ceramic capacitor close to pin for stability and transient response. |
| 2 GND | Power ground reference | Primary return path; exposed pad must be soldered to PCB GND plane for thermal management. |
| 3 EN | Enable control input | Logic-high (>0.9 V) enables regulation; logic-low (<0.4 V) disables output and activates 100 Ω discharge path. |
| 4 N/C | No-connect terminal | Internally unconnected; may be tied to GND to enhance thermal conduction from package body. |
| 5 OUT | Regulated output | Delivers stable 1.7 V; requires ≥1 µF X7R/X5R ceramic capacitor directly at pin for loop stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Rated for automotive applications (Grade 1: −40 °C to +125 °C ambient), PPAP-capable with unique site controls. |
| Active output discharge | 100 Ω internal pull-down activated during shutdown - prevents floating outputs and ensures fast VOUT decay in safety-critical systems. |
| Ultra-low IQ | 50 µA typical at zero load - minimizes standby power in battery-backed parking cameras with motion-triggered wake-up. |
| Stable with 1 µF ceramic | No ESR requirement on COUT - simplifies BOM by eliminating need for tantalum or polymer capacitors. |
| Thermal & current protection | Auto-recovering thermal shutdown (160 °C trip, 140 °C reset) and foldback current limit - protects against sustained overload or PCB trace faults. |
| High PSRR | 75 dB at 1 kHz - maintains clean 1.7 V supply despite ripple from buck converters powering adjacent subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8114ASN170T2G | Same electrical specs and TSOP-5 package; differs only in tape-and-reel quantity (10,000 pcs vs. 3,000 pcs). | Identical functional use; selected for high-volume production runs requiring larger reel sizes. | Choose when optimizing for line-side replenishment efficiency and minimizing changeover frequency. |
| TLV73317PDBVR | 1.7 V, 300 mA LDO with 250 mV dropout (vs. 170 mV), 65 µA IQ (vs. 50 µA), SOT-23-5 package, non-automotive grade. | Lacks AEC-Q100 qualification and active discharge; suitable for industrial or consumer portable devices only. | Select only for non-automotive designs where cost or footprint priority outweighs automotive reliability requirements. |
Compared with NCV8114ASN170T1G, the NCV8114ASN170T2G offers identical performance in higher-reel packaging, while TLV73317PDBVR trades automotive qualification and lower dropout for broader commercial availability - making the former ideal for volume automotive builds and the latter acceptable only in non-safety-critical contexts.

FAQ
What is the output voltage tolerance of the NCV8114ASN170T1G over temperature?
The NCV8114ASN170T1G 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 VOUT ≤ 2.0 V - which corresponds to ±2.94% at 1.7 V nominal. This is confirmed in the Electrical Characteristics table on page 3 of the datasheet.
Does the NCV8114ASN170T1G include active output discharge, and how does it behave?
Yes, the NCV8114ASN170T1G includes active output discharge. When the EN pin is driven below 0.4 V, the internal 100 Ω discharge transistor connects OUT to GND, pulling the output voltage to near-zero within microseconds. This function is exclusive to ASN variants (like NCV8114ASN170T1G) and is absent in BSN versions per the Ordering Information table on page 11.
What is the minimum recommended output capacitor for stable operation of the NCV8114ASN170T1G?
The NCV8114ASN170T1G is stable with a minimum 1 µF ceramic capacitor (X5R or X7R dielectric) placed directly at the OUT pin. The datasheet confirms stability down to 0.22 µF effective capacitance, accounting for DC bias and temperature derating - but 1 µF is the recommended value for robust performance across all conditions.
Can the NCV8114ASN170T1G operate with an input voltage lower than 1.7 V?
No. The absolute minimum operating input voltage for the NCV8114ASN170T1G is 1.7 V, as specified in the Recommended Operating Conditions table (page 3). Operation below this violates the device's safe operating area and may result in loss of regulation or undefined behavior - especially critical given its 170 mV dropout at full load.
Is the NCV8114ASN170T1G pin-compatible with other variants in the NCV8114 family?
Yes, all NCV8114 variants - including NCV8114ASN170T1G, NCV8114ASN330T1G, and NCV8114BSN180T1G - share identical TSOP-5 pinout and mechanical footprint (Case 483). However, ASN and BSN variants differ in active discharge functionality, so system-level enable logic must be verified for functional equivalence.
