Product details
Overview
NCP717BMX150TCG from onsemi is a 300 mA, fixed 1.5 V output low-dropout (LDO) regulator in XDFN-4 1.0×1.0 mm package, featuring 25 µA typical quiescent current, 22 µVRMS output noise (100 Hz–100 kHz), and 175 mV typical dropout at 300 mA - optimized for battery-powered portable electronics requiring ultra-low power and high noise immunity.
For engineers reviewing the NCP717BMX150TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its absence of active output discharge (distinguishing it from A/C variants), ±2% output accuracy over load/line/temperature, stability with 1 µF ceramic output capacitor, and EN-controlled enable/disable functionality with 0.4 V/0.9 V thresholds.
Technical Context
The NCP717BMX150TCG employs a PMOS pass transistor architecture enabling low dropout and inherent reverse-current blocking. Its adaptive quiescent current circuitry dynamically reduces ground current to 25 µA at no-load while maintaining regulation, critical for extended battery life in always-on subsystems.
Unlike versions with active discharge (e.g., NCP717AMX150TCG), the "B" suffix denotes omission of the internal discharge FET - meaning the output remains floating during shutdown, requiring external discharge if needed. It delivers 70 dB PSRR at 1 kHz and maintains stability across −40°C to +125°C junction temperature with minimal external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% over load/line/temperature - ensures stable core voltage for low-power MCUs and RF ICs without external feedback. |
| Max Output Current | 300 mA continuous - supports moderate-power peripherals like Bluetooth transceivers or sensor hubs. |
| Quiescent Current | 25 µA typical at no-load - extends battery runtime in standby modes of wearables and IoT edge nodes. |
| Dropout Voltage | 175 mV typical at 300 mA - enables operation down to VIN = 1.675 V, compatible with single-cell Li-ion/Li-poly discharged states. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz) - meets stringent noise requirements for ADC references and RF power amplifiers. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding the same battery rail. |
| Enable Threshold | 0.4 V (low) / 0.9 V (high) - compatible with standard GPIO logic levels and supports clean sequencing in multi-rail systems. |
Pinout & Package
XDFN-4 1.0×1.0 mm, 0.65 mm pitch, exposed thermal pad (EPAD) - compact footprint ideal for space-constrained mobile PCBs; EPAD must be soldered to GND plane for thermal performance and EMI reduction.
| 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 thermal path; connects directly to EPAD and system GND plane. |
| 3 (EN) | Enable control input | Logic-high (>0.9 V) enables regulator; logic-low (<0.4 V) disables output (no active discharge). |
| 4 (IN) | Input supply | Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor close to pin to suppress input ripple and EMI. |
| EPAD | Thermal & electrical ground | Must be soldered to large GND copper area - reduces θJA from 250°C/W to ~120°C/W in typical layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 25 µA typical at zero load - enables >1-year battery life in coin-cell-powered sensors with periodic wake-up. |
| No active discharge | "B" variant omits internal discharge FET - avoids unintended discharge of backup rails or analog reference nodes during shutdown. |
| Low-noise regulation | 22 µVRMS noise floor - eliminates need for additional LC filtering in precision analog signal chains. |
| Robust protection | Integrated thermal shutdown (160°C) and current limit (379 mA typ.) - prevents damage during overload or PCB fault conditions. |
| Small-footprint stability | Stable with 1 µF ceramic COUT - reduces BOM count and board area vs. legacy LDOs requiring 10–22 µF tantalum. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B152MR-G | 1.5 V fixed, 200 mA, 1 µA IQ, SOT-25 package (2.9×2.8 mm) | Lower current rating and larger footprint; lacks EN pin and thermal shutdown | Select when ultra-low IQ dominates over current capability and board space is not constrained. |
| Micrel MIC5205-1.5YM5-TR | 1.5 V fixed, 150 mA, 80 µA IQ, SOT-23-5 package | Half the output current; higher quiescent current; includes active discharge | Choose only for legacy designs where SOT-23-5 footprint is mandatory and 150 mA suffices. |
Compared with XC6210B152MR-G and MIC5205-1.5YM5-TR, the NCP717BMX150TCG uniquely balances 300 mA drive, 25 µA IQ, EN control, and XDFN-4 miniaturization - making it optimal for next-gen portable medical and wireless edge devices where size, efficiency, and feature integration are co-prioritized.

FAQ
What is the output voltage tolerance of the NCP717BMX150TCG over temperature and load?
The NCP717BMX150TCG maintains ±2% output voltage accuracy across −40°C to +125°C junction temperature, full 0–300 mA load range, and input voltage from VOUT(nom)+0.5 V to 5.5 V. This is verified per Electrical Characteristics Table on page 3 of the datasheet, ensuring reliable operation in thermally demanding portable environments without external trimming.
Does the NCP717BMX150TCG include active output discharge?
No, the NCP717BMX150TCG does not include active output discharge. The "B" suffix explicitly denotes absence of the internal discharge FET - unlike "A" (1.2 kΩ) or "C" (120 Ω) variants. When EN is pulled low, the output floats; external discharge circuitry is required if rapid VOUT decay is needed.
What is the minimum output capacitance required for stability with the NCP717BMX150TCG?
The NCP717BMX150TCG is stable with a minimum 1.0 µF ceramic output capacitor (X5R/X7R), and remains stable down to 100 nF under typical conditions. The datasheet confirms stability across ESR < 700 mΩ and emphasizes avoiding tantalum capacitors due to their high/temperature-variable ESR - critical for predictable transient behavior in portable designs.
How does the NCP717BMX150TCG achieve ultra-low quiescent current?
The NCP717BMX150TCG uses dynamic quiescent current adjustment: its internal bias circuitry scales ground current with load, achieving 25 µA typical at no-load while maintaining regulation. As load increases to 300 mA, ground current rises to 250 µA - balancing efficiency and performance without compromising startup time or PSRR.
Can the NCP717BMX150TCG operate from a 1.8 V input supply?
Yes, the NCP717BMX150TCG operates from 1.8 V to 5.5 V input. With a 1.5 V output, minimum functional input is 1.675 V (1.5 V + 175 mV dropout), so 1.8 V provides 125 mV headroom - sufficient for stable regulation at light-to-moderate loads. At full 300 mA, dropout rises to ~190 mV (per datasheet Table, page 3), still within margin.
