Product details
Overview
NCV8114BSN120T1G from onsemi is a 300 mA, 1.2 V fixed-output CMOS low-dropout linear regulator optimized for automotive and noise-sensitive portable applications. It delivers ±1% output accuracy at room temperature, 135 mV typical dropout at 300 mA, and 75 dB PSRR at 1 kHz, operating from 1.7 V to 5.5 V input with dynamic quiescent current adjustment (typ. 50 µA at no-load).
For engineers reviewing the NCV8114BSN120T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, TSOP-5 package compatibility, absence of active output discharge (distinguishing it from ASN variants), stable operation with 1 µF ceramic output capacitor, and thermal shutdown/current limit protection for robust battery-powered system design.
Technical Context
The NCV8114BSN120T1G integrates a PMOS pass transistor with internal bandgap reference, enable logic, thermal shutdown, and current-limit circuitry. Its dynamic IQ adjustment enables ultra-low standby current (typ. 0.1 µA) while maintaining fast load transient response - critical for always-on automotive modules like parking cameras.
Unlike ASN-series variants, this BSN version omits the active output discharge function (RDIS = open), confirmed by ordering information and functional description. It operates across −40°C to +125°C ambient, with thermal shutdown triggered at 160°C (140°C hysteresis), and requires no minimum ESR output capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±1% at room temperature - ensures precise core voltage for low-power MCUs and sensors without external feedback. |
| Max Output Current | 300 mA continuous - supports moderate-power peripherals such as image sensors or RF transceivers in compact modules. |
| Dropout Voltage | 135 mV typical at 300 mA - enables regulation from 1.335 V input, extending battery runtime in single-cell Li-ion or LiFePO₄ systems. |
| Quiescent Current | Typ. 50 µA at no-load, typ. 0.1 µA in shutdown - minimizes leakage in always-on automotive subsystems with strict sleep-current budgets. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters, preserving signal integrity in analog front-ends. |
| Input Voltage Range | 1.7 V to 5.5 V - compatible with wide-input automotive power rails and multi-cell battery configurations. |
| Operating Temp | −40°C to +125°C ambient - validated for under-hood and infotainment environments per AEC-Q100 Grade 1. |
Pinout & Package
NCV8114BSN120T1G 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 for enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Regulator input supply | Accepts 1.7–5.5 V; requires ≥1 µF ceramic capacitor to ground for stability and transient immunity. |
| 2 - GND | Power ground reference | Primary return path; must be connected to low-impedance PCB ground plane and tied directly to exposed thermal pad. |
| 3 - EN | Enable control input | Logic-high (>0.9 V) enables regulation; logic-low (<0.4 V) disables output and reduces IQ to 0.1 µA - no active discharge. |
| 4 - N/C | No-connect terminal | Internally unconnected; may be grounded to improve thermal dissipation without electrical impact. |
| 5 - OUT | Regulated 1.2 V output | Delivers up to 300 mA; requires ≥1 µF X5R/X7R ceramic capacitor to ground for guaranteed stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 1 (−40°C to +125°C) compliance with PPAP capability - meets automotive OEM reliability and traceability requirements. |
| Low-noise regulation | 70 µVRMS output noise (10 Hz–100 kHz) - suitable for powering ADC references and RF synthesizers without added filtering. |
| Robust protection suite | Thermal shutdown (160°C), current limit (600 mA typ.), and short-circuit immunity - eliminates need for external fault management circuitry. |
| Minimal external components | Stable with only two 1 µF ceramic capacitors (CIN, COUT) - reduces BOM count and PCB area in space-constrained modules. |
| Ultra-low shutdown IQ | 0.1 µA typical - enables >10-year battery life in maintenance-free telematics or sensor nodes with periodic wake-up cycles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8114ASN120T1G | Includes active output discharge (100 Ω pull-down on OUT during shutdown); otherwise identical specs and pinout. | Required where rapid VOUT discharge prevents back-powering or latch-up in multi-rail systems. | Select NCV8114ASN120T1G only if active discharge is explicitly needed; NCV8114BSN120T1G is preferred for simpler, lower-cost implementations without discharge requirement. |
| TLD1120FV | 250 mA, 1.2 V fixed LDO; AEC-Q100 Grade 1; higher dropout (200 mV @ 250 mA); no enable pin. | Lacks EN control and has lower current rating - suitable only for non-enabling, lower-power legacy designs. | Use TLD1120FV only when EN functionality is unnecessary and 300 mA output is not required; NCV8114BSN120T1G offers superior performance and flexibility. |
Compared with NCV8114ASN120T1G, the NCV8114BSN120T1G removes active discharge to reduce complexity and cost, while retaining identical regulation accuracy, PSRR, and thermal protection - making it optimal for cost-sensitive automotive modules where discharge is unused. Versus TLD1120FV, it adds enable control, higher output current, and lower dropout for improved system efficiency and design versatility.

FAQ
What is the output voltage tolerance of the NCV8114BSN120T1G over temperature?
The NCV8114BSN120T1G guarantees ±1% output voltage accuracy at room temperature. Over the full operating range (−40°C to +125°C), output voltage deviation is specified as ±50 mV for VOUT ≤ 2.0 V - which corresponds to ±4.2% for the 1.2 V nominal output. This is confirmed in the Electrical Characteristics table under "Output Voltage Accuracy" with test conditions TJ = −40°C to +125°C.
Does the NCV8114BSN120T1G include active output discharge functionality?
No, the NCV8114BSN120T1G does not include active output discharge. Per the Ordering Information table and Applications Information section, only ASN-series variants (e.g., NCV8114ASN120T1G) feature the 100 Ω discharge resistor. The BSN suffix explicitly denotes "without output active discharge function", and the EN pin behavior in shutdown mode is limited to pass transistor turn-off and ultra-low IQ draw.
What is the minimum output capacitor required for stability with the NCV8114BSN120T1G?
The NCV8114BSN120T1G is stable with a minimum 1 µF ceramic (X5R or X7R) output capacitor. The datasheet confirms stability down to 0.22 µF to accommodate capacitance loss due to DC bias and temperature, but 1 µF is the recommended value for guaranteed performance across all conditions - including worst-case ESR and temperature extremes.
Can the NCV8114BSN120T1G operate from a 1.5 V input supply?
No, the NCV8114BSN120T1G cannot reliably regulate from a 1.5 V input. Its absolute minimum input voltage is 1.7 V per Recommended Operating Conditions. At 1.2 V output, the minimum functional input is 1.335 V (1.2 V + 135 mV dropout), but the device will not power up or meet specifications below 1.7 V - as confirmed in both Absolute Maximum Ratings and Electrical Characteristics tables.
Is the NCV8114BSN120T1G pin-compatible with other variants in the NCV8114 family?
Yes, the NCV8114BSN120T1G is pin-compatible with all NCV8114 variants in the TSOP-5 package, including ASN-series parts. Pin assignments (IN, GND, EN, N/C, OUT) and mechanical footprint are identical across the family, enabling drop-in replacement for different output voltages or discharge requirements - provided board-level enable logic and output capacitor selection align with the selected variant's features.
