Product details
Overview
NCP114ASN150T2G from onsemi is a 300 mA low-dropout linear regulator (LDO) delivering 1.5 V output with ±1% accuracy at room temperature, 135 mV typical dropout at 300 mA, and 75 dB PSRR at 1 kHz-designed for noise-sensitive, space-constrained battery-powered applications such as smartphones and portable medical devices.
For engineers reviewing the NCP114ASN150T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.7–5.5 V input range, 50 µA typical quiescent current, thermal shutdown and current limit protection, stability with 1 µF ceramic output capacitor, and TSOP-5 package compatibility with standard PCB layouts.
Technical Context
The NCP114ASN150T2G implements a PMOS pass transistor architecture enabling low dropout and inherent reverse-current blocking. Its dynamic quiescent current adjustment minimizes IQ under light/no-load conditions while maintaining regulation integrity across −40°C to +85°C junction temperature.
It integrates enable logic with 0.9 V turn-on and 0.4 V turn-off thresholds, thermal shutdown at 160°C (20°C hysteresis), and output current limiting at 300–600 mA. The device supports active output discharge only in "A"-suffix variants-not applicable to NCP114ASN150T2G, which uses the "B"-suffix TSOP-5 configuration without discharge function.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±1% at room temperature - ensures stable core or I/O rail for low-voltage digital ICs. |
| Max Output Current | 300 mA continuous - sufficient for powering microcontrollers, sensors, or RF front-ends in portable systems. |
| Dropout Voltage | 160 mV typical at 300 mA (TSOP-5) - enables operation down to VIN = 1.66 V while sustaining 1.5 V output. |
| Quiescent Current | 50 µA typical at no load - extends battery life in always-on or sleep-mode subsystems. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Stability | Guaranteed with ≥1 µF X5R/X7R ceramic output capacitor - eliminates need for tantalum or high-ESR alternatives. |
| Operating Input Range | 1.7 V to 5.5 V - compatible with single-cell Li-ion (2.7–4.2 V), LiFePO₄ (2.0–3.6 V), or 3.3 V/5 V system rails. |
Pinout & Package
Package: TSOP-5 (Case 483), 3.00 × 1.50 × 0.95 mm, Pb-free, exposed pad connected to GND for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output voltage | Delivers 1.5 V; requires ≥1 µF ceramic capacitor to GND for stability and transient response. |
| 2 (IN) | Input supply connection | Accepts 1.7–5.5 V; benefits from local 1 µF ceramic decoupling to suppress input ripple and trace inductance effects. |
| 3 (GND) | Power ground reference | Primary return path; exposed pad must be soldered directly to large GND copper plane for thermal management. |
| 4 (N/C) | No-connect terminal | Internally unconnected; may be tied to GND to improve thermal conduction without electrical impact. |
| 5 (EN) | Enable control input | Logic-high (>0.9 V) enables regulation; logic-low (<0.4 V) disables output and reduces IQ to ~0.01 µA. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 50 µA typical at no load - preserves battery capacity in standby and intermittent-use modes. |
| High PSRR at 1 kHz | 75 dB - mitigates noise coupling from noisy system power rails into sensitive analog or RF circuitry. |
| Thermal shutdown protection | 160°C trip with 20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| Current limit safeguard | 300–600 mA foldback - protects against short-circuit faults while allowing safe startup into capacitive loads. |
| Single-supply enable interface | 0.4 V/0.9 V logic thresholds - compatible with 1.8 V or 3.3 V GPIO without level-shifting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/MB | 250 mA max output, 1.5 V fixed, 1.6–6.0 V input, 1.8 µA IQ - significantly lower quiescent current but lower current capability. | Better suited for micropower sensor nodes; insufficient for 300 mA peak loads like RF transceivers. | Select when ultra-low IQ dominates over output current; verify load transient response with 1 µF COUT. |
| TLS850B2TE/V1 | 500 mA, 1.5 V fixed, 2.7–40 V input, integrated watchdog and reset - automotive-grade AEC-Q100 qualified with higher VIN range. | Designed for automotive body electronics; overqualified and costlier for consumer portable use. | Choose only if automotive qualification, extended input range, or system monitoring features are required. |
Compared with MCP1700T-1502E/MB and TLS850B2TE/V1, the NCP114ASN150T2G delivers optimal balance of 300 mA drive, 50 µA IQ, and 1.7–5.5 V flexibility for mainstream portable electronics-without over-engineering for micropower or automotive extremes.

FAQ
What is the output voltage tolerance of the NCP114ASN150T2G over temperature?
The NCP114ASN150T2G maintains ±1% output voltage accuracy at room temperature (25°C). Over the full operating junction temperature range of −40°C to +85°C, output voltage deviation remains within ±2% for 1.5 V output, as specified in the Electrical Characteristics table under "Output Voltage Accuracy" for VOUT > 2.0 V (scaled per datasheet note).
Does the NCP114ASN150T2G include active output discharge?
No, the NCP114ASN150T2G does not include active output discharge. Per the ordering information table, only "A"-suffix variants (e.g., NCP114AMX150TCG) feature this function. The "B"-suffix TSOP-5 part NCP114ASN150T2G omits the discharge transistor, resulting in slower output decay during disable.
What is the minimum output capacitance required for stability with the NCP114ASN150T2G?
The NCP114ASN150T2G is stable with a minimum 1 µF X5R or X7R ceramic output capacitor. The datasheet confirms stability down to 0.22 µF effective capacitance (accounting for DC bias and temperature derating), but 1 µF is the recommended nominal value for guaranteed performance across all conditions.
Can the NCP114ASN150T2G operate from a 1.8 V input while delivering 1.5 V output?
Yes - with a 1.8 V input, the NCP114ASN150T2G sustains regulation because its typical dropout voltage at 300 mA in TSOP-5 is 160 mV. Since 1.8 V − 0.16 V = 1.64 V > 1.5 V, it operates well within dropout margin. At lighter loads, dropout falls further, improving efficiency and thermal performance.
What thermal resistance does the NCP114ASN150T2G exhibit in its TSOP-5 package?
In the TSOP-5 package (Case 483), the NCP114ASN150T2G has a junction-to-ambient thermal resistance (RJA) of 236°C/W when mounted on a standard 1 oz FR-4 PCB with 645 mm² copper area. This value assumes proper GND pad connection and influences maximum allowable power dissipation in thermally constrained layouts.
