Product details
Overview
NCP114BMX150TCG from onsemi is a 300 mA CMOS low-dropout linear regulator delivering a fixed 1.5 V output with ±1% accuracy at room temperature, 135 mV typical dropout at full load, and 75 dB PSRR at 1 kHz - optimized for noise-sensitive, space-constrained battery-powered applications such as smartphones and portable medical devices.
For engineers reviewing the NCP114BMX150TCG 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 UDFN4 package compatibility with high-density PCB layouts.
Technical Context
The NCP114BMX150TCG employs a PMOS pass transistor architecture enabling ultra-low dropout and inherent reverse-current blocking. Its dynamic quiescent current adjustment minimizes IQ under no-load conditions while maintaining regulation 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 600 mA typical. Unlike version-A variants, this B-suffix device lacks active output discharge functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±1% at 25°C; ensures stable core voltage for 1.5 V logic rails without external feedback. |
| Max Output Current | 300 mA continuous; supports moderate-power RF modules or sensor subsystems in portable designs. |
| Dropout Voltage | 135 mV typical at 300 mA; enables operation down to VIN = 1.635 V, critical for single-cell Li-ion or Li-poly systems. |
| Quiescent Current | 50 µA typical at no load; extends battery life in always-on monitoring modes (e.g., wearable health sensors). |
| PSRR | 75 dB at 1 kHz; suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Input Voltage Range | 1.7 V to 5.5 V; compatible with coin cells, single-cell Li-ion (2.7–4.2 V), and regulated 3.3/5 V system supplies. |
| Stability | Guaranteed with ≥1 µF X5R/X7R ceramic output capacitor; eliminates need for tantalum or electrolytic alternatives. |
Pinout & Package
Package: UDFN4 (1.0 mm × 1.0 mm, 0.65 mm pitch, exposed pad), Case 517CU - thermally enhanced for compact, low-profile applications requiring efficient heat dissipation via GND-connected copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply connection | Accepts 1.7–5.5 V; requires local 1 µF ceramic decoupling to ground for transient immunity. |
| 2 (GND) | Power ground reference | Primary return path; exposed pad must be soldered directly to PCB ground plane for thermal and electrical integrity. |
| 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. |
| 4 (OUT) | Regulated output | Delivers 1.5 V ±1%; requires ≥1 µF ceramic capacitor to ground for loop stability and load transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 50 µA typical at no load - enables multi-week standby in battery-operated IoT edge nodes. |
| Low-noise regulation | 70 µVrms output noise (10 Hz–100 kHz); suitable for ADC reference supplies and RF front-end biasing. |
| Robust protection | Thermal shutdown (160°C), current limit (600 mA), and short-circuit safe operation - eliminates need for external fault management. |
| Small-footprint packaging | UDFN4 1.0×1.0 mm - saves >60% board area vs. TSOP-5; ideal for wearables and hearing aids. |
| Wide input compatibility | Operates from 1.7 V - supports direct connection to partially discharged Li-ion cells (≥2.5 V nominal). |

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; 170 mV dropout at 250 mA; 1.8 µA IQ; SOT-23-5 package | Limited to lower current loads; better for ultra-low-power microcontrollers but unsuitable for RF power amplifiers | Select when IQ < 2 µA is mandatory and load current ≤250 mA; avoid if 300 mA peak burst current is required. |
| Torex XC6210B152MR-G | 300 mA output; 120 mV dropout at 300 mA; 1 µA IQ; SOT-25 package; no enable pin | Lacks EN control and thermal shutdown; requires external enable circuitry for sequencing | Choose for cost-sensitive, always-on applications where enable functionality and fault protection are not needed. |
Compared with MCP1700T-1502E/MB and XC6210B152MR-G, the NCP114BMX150TCG uniquely balances 300 mA capability, 135 mV dropout, 50 µA IQ, integrated EN control, and full protection - making it optimal for compact, battery-powered systems demanding both performance and reliability.

FAQ
What is the output voltage tolerance of the NCP114BMX150TCG over temperature?
The NCP114BMX150TCG maintains ±1% output voltage accuracy at room temperature (25°C). Over the full operating junction temperature range (−40°C to +85°C), the datasheet specifies ±40 mV deviation for VOUT ≤ 2.0 V - which corresponds to ±2.67% for the 1.5 V output. This ensures reliable operation in consumer-grade portable environments without requiring calibration.
Does the NCP114BMX150TCG include active output discharge?
No, the NCP114BMX150TCG does not include active output discharge. The "B" suffix explicitly denotes the absence of this feature - only "A"-suffix variants (e.g., NCP114AMX150TCG) integrate the 100 Ω active discharge resistor. For applications requiring fast VOUT ramp-down during disable, an external discharge circuit or A-suffix variant must be selected.
What is the minimum output capacitance required for stability with the NCP114BMX150TCG?
The NCP114BMX150TCG is guaranteed stable with a minimum 1 µF X5R or X7R ceramic capacitor on the OUT pin. The datasheet confirms stability down to 0.22 µF effective capacitance - accounting for DC bias and temperature derating - making 0402-size 1 µF capacitors fully viable in space-constrained layouts.
Can the NCP114BMX150TCG operate from a single alkaline cell?
Yes - the NCP114BMX150TCG supports input voltages as low as 1.7 V, well within the 1.0–1.6 V discharge curve of a single alkaline AA/AAA cell. With its 135 mV dropout, it delivers regulated 1.5 V output until the cell drops below ~1.635 V, maximizing usable battery energy in low-power remote controls or sensors.
How does the thermal performance of the NCP114BMX150TCG compare between UDFN4 and TSOP-5 packages?
In the UDFN4 package (Case 517CU), the NCP114BMX150TCG has a junction-to-air thermal resistance (RJA) of 170°C/W on a 1 oz FR-4 board with 645 mm² copper area. In contrast, the TSOP-5 package (Case 483) exhibits 236°C/W under identical conditions - making the UDFN4 version significantly more thermally efficient and better suited for high ambient temperature or high-current-density applications.
