Product details
Overview
NCP114BMX100TCG from onsemi is a 300 mA CMOS low-dropout linear regulator delivering 1.0 V output with ±1% accuracy, 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 NCP114BMX100TCG datasheet, pinout, applications, or equivalent options, key selection criteria include quiescent current (50 µA typ), standby current (0.1 µA typ), UDFN4 1×1 mm package compatibility, and absence of active output discharge function (B-suffix variant).
Technical Context
The NCP114BMX100TCG employs a PMOS pass transistor architecture enabling ultra-low quiescent current via dynamic IQ adjustment, supporting stable regulation across 1.7–5.5 V input while maintaining 1.0 V output under 300 mA load. Its internal bandgap reference and active current-limit protection ensure precision and robustness in portable systems.
Unlike A-suffix variants, the B-suffix NCP114BMX100TCG omits active output discharge (RDIS = open), simplifying shutdown behavior: EN < 0.4 V disables regulation and reduces VIN current to 0.01 µA typ, with no intentional pull-down of VOUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0 V ±1% at room temperature - ensures precise core voltage for low-power microcontrollers and sensors. |
| Max Output Current | 300 mA continuous - sufficient for single-core SoCs or RF front-ends in handheld devices. |
| Dropout Voltage | 135 mV typical at 300 mA - enables operation down to 1.135 V input, extending battery runtime in Li-ion and coin-cell systems. |
| Quiescent Current | 50 µA typical at no load - minimizes standby power loss in always-on subsystems. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding the same battery rail. |
| Stability | Guaranteed with 1 µF ceramic output capacitor - eliminates need for tantalum or high-ESR capacitors, reducing BOM cost and footprint. |
| Protection | Thermal shutdown (160°C) and current limit (600 mA typ) - prevents damage during overload or PCB thermal runaway. |
Pinout & Package
Package: UDFN4 (1.0 × 1.0 mm, 0.65 mm pitch), Pb-free, exposed thermal pad connected to GND. Optimized for high-density portable PCB layouts with minimal thermal resistance (RJA = 170°C/W on 1 oz FR-4).
| 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 stability and transient response. |
| 2 (GND) | Power ground reference | Primary return path; exposed pad must be soldered directly to large GND copper area for thermal management. |
| 3 (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 - no active discharge. |
| 4 (OUT) | Regulated output | Delivers stable 1.0 V; requires 1 µF ceramic capacitor to ground; supports up to 300 mA load with ≤30 mV load regulation (UDFN). |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic quiescent current adjustment | Reduces IQ from 50 µA (no load) to sub-µA levels under light loads - extends battery life in intermittent wake-up systems. |
| No active output discharge | VOUT floats during disable (B-suffix); avoids unintended discharge of backup capacitors or biasing of downstream circuitry. |
| Ultra-low-noise regulation | 70 µVRMS output noise (10 Hz–100 kHz) - suitable for ADC references and RF synthesizer supplies without additional filtering. |
| Wide input voltage range | Operates from 1.7 V (single alkaline) to 5.5 V (USB-powered) - supports multi-chemistry battery systems and mixed-rail designs. |
| Robust thermal design | 170°C/W junction-to-ambient thermal resistance with standard layout - enables 300 mA operation at +85°C ambient without heatsinking. |
Applications
| Smartphone Baseband Power | Wearable Sensor Hub |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1002E/TT | 250 mA max output, 170 mV dropout at 250 mA, no enable pin, SOT-23-3 package | Lacks EN control and thermal shutdown; unsuitable for systems requiring remote power gating or high-temp reliability | Select only for simple, low-current, always-on rails where board space permits SOT-23 and enable functionality is unnecessary. |
| Torex XC6210B102MR-G | 200 mA max output, 120 mV dropout at 200 mA, 1.0 V fixed, UDFN-4 1.0×1.0 mm, no active discharge | Lower current rating and slightly lower PSRR (70 dB); identical footprint but not pin-compatible due to different pin 1 (IN vs OUT) assignment | Consider for cost-sensitive designs where 200 mA suffices and layout can accommodate pin reassignment; verify thermal performance at 85°C. |
Compared with MCP1700T-1002E/TT and XC6210B102MR-G, the NCP114BMX100TCG delivers higher output current (300 mA vs ≤250 mA), superior PSRR (75 dB vs ≤70 dB), and integrated enable control - making it optimal for next-generation portable electronics requiring dynamic power management and robust thermal protection.

FAQ
What is the output voltage tolerance of the NCP114BMX100TCG over temperature?
The NCP114BMX100TCG 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 ±2% total accuracy for VOUT > 2.0 V - but since this part is 1.0 V, the absolute tolerance is ±40 mV (±4%) per the "VOUT ≤ 2.0 V" row in Electrical Characteristics. This ensures reliable operation for 1.0 V logic domains across industrial temperature ranges.
Does the NCP114BMX100TCG include active output discharge?
No, the NCP114BMX100TCG does not include active output discharge. The 'B' suffix explicitly denotes the absence of this feature - unlike 'A'-suffix variants (e.g., NCP114AMX100TCG), which integrate a 100 Ω discharge FET. When EN is pulled low, the NCP114BMX100TCG simply disables regulation and leaves VOUT floating; external discharge circuitry is required if rapid VOUT decay is needed.
What is the minimum output capacitor required for stability with the NCP114BMX100TCG?
The NCP114BMX100TCG is stable with a minimum 1 µF X5R or X7R ceramic capacitor on the OUT pin. The datasheet confirms stability down to 0.22 µF accounting for DC bias and temperature derating, but 1 µF is the recommended value to ensure margin across all conditions. Tantalum capacitors are discouraged due to high ESR (>2 Ω maximum allowed), which risks instability.
Can the NCP114BMX100TCG operate from a 1.8 V input supply?
Yes, the NCP114BMX100TCG operates from 1.7 V to 5.5 V input. With a 1.0 V output and 135 mV typical dropout, it functions reliably down to 1.135 V input - so 1.8 V provides ample headroom (665 mV). At 1.8 V input, the device delivers full 300 mA output while maintaining regulation, low noise, and thermal safety - ideal for dual-cell NiMH or single-cell LiFePO₄ systems.
What package type and dimensions does the NCP114BMX100TCG use?
The NCP114BMX100TCG uses the UDFN4 (1.0 × 1.0 mm, 0.65 mm pitch) package, case 517CU. It features four terminals (IN, GND, EN, OUT) and an exposed thermal pad that must be soldered to a GND plane. Height is 0.55 mm max. This compact, thermally efficient package is RoHS-compliant and optimized for high-density portable PCBs.
