Product details
Overview
NCP707BMX150TCG from onsemi is a 200 mA low-dropout (LDO) voltage regulator with fixed 1.5 V output, optimized for battery-powered portable electronics. It delivers ±2% output accuracy over load/line/temperature, achieves 100 mV typical dropout at 200 mA, and features ultra-low 25 µA quiescent current and 22 µVRMS output noise (100 Hz–100 kHz) - enabling stable, quiet power in space-constrained, noise-sensitive applications like GPS modules and Bluetooth handsets.
For engineers reviewing the NCP707BMX150TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its XDFN-4 1.0×1.0 mm package, EN-controlled enable/disable functionality, stability with 1 µF ceramic output capacitor, and thermal shutdown/current limit protections - all critical for compact, reliable low-power system design.
Technical Context
The NCP707BMX150TCG employs a PMOS pass transistor architecture with adaptive ground current control to maintain 25 µA quiescent current at no-load while supporting up to 200 mA output. Its internal soft-start prevents output overshoot during turn-on, and the EN pin provides logic-level control with 0.4 V low-threshold and 0.9 V high-threshold, plus built-in 56 mV hysteresis to reject noise-induced toggling.
It integrates thermal shutdown (160°C trip, 20°C hysteresis) and foldback current limiting (379 mA typical), and achieves 70 dB PSRR at 1 kHz. Unlike versions A and C, the B suffix indicates no active output discharge function - confirmed by absence of RDIS specification and omission from the "Active discharge function is present only in NCP707AMXyyyTCG and NCP707CMXyyyTCG" statement in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% - ensures precise biasing for low-voltage logic, RF front-ends, and sensor analog circuitry without external feedback components. |
| Max Output Current | 200 mA continuous - sufficient for powering microcontrollers, wireless SoCs, and small displays in portable devices. |
| Dropout Voltage | 100 mV typical at 200 mA - enables regulation from 1.6 V input, extending battery runtime in single-cell Li-ion or NiMH systems. |
| Quiescent Current | 25 µA typical at no-load - minimizes standby power loss, critical for multi-year battery life in IoT sensors and wearables. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz) - low enough to avoid degrading SNR in ADCs, audio codecs, and RF receivers. |
| PSRR | 70 dB at 1 kHz - suppresses ripple from noisy switching supplies, reducing need for additional filtering stages. |
| Input Voltage Range | 1.8 V to 5.5 V - compatible with wide range of battery chemistries and intermediate supply rails. |
Pinout & Package
XDFN-4 1.0×1.0 mm package with exposed pad (EPAD) for thermal dissipation; requires soldering EPAD directly to GND plane for optimal thermal performance (RJA = 250°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers stable 1.5 V; requires ≥1 µF ceramic capacitor to GND for stability and transient response. |
| 2 - GND | Power ground | Reference node for regulation and protection circuits; must be connected to large copper pour for thermal management. |
| 3 - EN | Enable control input | Logic-high (>0.9 V) enables regulator; logic-low (<0.4 V) disables it with <1 µA shutdown current - no active discharge on B variant. |
| 4 - IN | Input supply | Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor close to pin to suppress input transients and EMI. |
| EPAD | Thermal pad | Must be soldered to GND plane; primary path for heat removal - essential to meet 125°C max junction temperature rating. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 25 µA at no-load - extends shelf life and operational runtime in always-on battery-powered devices. |
| Low-noise regulation | 22 µVRMS output noise - eliminates need for post-LDO LC filtering in sensitive analog signal chains. |
| Stable with minimal capacitance | Guaranteed stability with 1 µF ceramic output capacitor - reduces BOM count and PCB area vs. legacy LDOs requiring 10+ µF. |
| Robust protection suite | Integrated thermal shutdown, current limiting, and reverse-voltage safe operation (body diode managed) - eliminates need for external protection components. |
| Small-footprint packaging | XDFN-4 1.0×1.0 mm - fits into tight spaces on wearable PCBs and miniaturized modules where board real estate is premium. |

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/TT | 250 mA rated, 1.8 µA IQ, 1.5 V fixed, SOT-23-5 package - lower IQ but larger footprint and higher dropout (330 mV @ 250 mA). | Preferred for ultra-long-life coin-cell applications; less suitable for high-current bursts due to higher dropout and thermal limits. | Select when minimum standby current dominates over size and transient performance. |
| Torex XC6210B152MR-G | 200 mA rated, 1 µA IQ, 1.5 V fixed, SOT-25 package - ultra-low IQ but only 45 dB PSRR at 1 kHz and no thermal shutdown. | Suitable for simple always-on sensors; not recommended for RF or mixed-signal systems requiring noise immunity and fault protection. | Select only for cost-sensitive, non-safety-critical, low-PSRR applications with strict IQ budgets. |
Compared with MCP1700T-1502E/TT and XC6210B152MR-G, the NCP707BMX150TCG offers superior noise performance (22 µVRMS vs. >40 µVRMS), integrated thermal shutdown, and smaller XDFN-4 footprint - making it the preferred choice for space-constrained, noise-sensitive, and safety-aware portable designs.

FAQ
What is the output voltage tolerance of the NCP707BMX150TCG over temperature and load?
The NCP707BMX150TCG maintains ±2% output voltage accuracy across −40°C to +125°C junction temperature, full 0–200 mA load range, and input voltage from VOUT + 0.5 V to 5.5 V. This is verified per Electrical Characteristics table on page 3 of the datasheet, ensuring reliable biasing for precision analog and digital circuits without external trimming.
Does the NCP707BMX150TCG include active output discharge?
No, the NCP707BMX150TCG does not include active output discharge. The datasheet explicitly states this feature is present only in NCP707AMXyyyTCG and NCP707CMXyyyTCG variants. The B suffix denotes standard enable/disable functionality without pull-down resistance on the OUT pin during shutdown.
What is the minimum output capacitor required for stability with the NCP707BMX150TCG?
The NCP707BMX150TCG is stable with a minimum 1.0 µF ceramic (X5R/X7R) output capacitor. The datasheet confirms stability down to 100 nF effective capacitance, but recommends ≥1.0 µF to accommodate DC bias, temperature, and tolerance derating - ensuring robust performance across production lots and operating conditions.
How does the NCP707BMX150TCG handle thermal overload?
The NCP707BMX150TCG activates thermal shutdown at 160°C junction temperature (typical), disabling the pass transistor until die temperature falls below ~140°C (20°C hysteresis). This protects against catastrophic failure during sustained overload or poor PCB thermal design, and is fully specified in the Absolute Maximum Ratings and Electrical Characteristics tables.
Can the NCP707BMX150TCG operate from a 1.6 V input supply?
No - the absolute minimum input voltage is 1.8 V per the Absolute Maximum Ratings table. At 1.5 V output and 100 mV typical dropout, the theoretical minimum input is 1.6 V, but the device is not characterized or guaranteed to operate below 1.8 V. Operating below this risks regulation loss, instability, or undefined behavior.
