Product details
Overview
NCP717AMX150TCG from onsemi is a 300 mA, fixed 1.5 V output, low-dropout linear regulator with active output discharge, designed for noise-sensitive portable electronics. It delivers ±2% output accuracy over load/line/temperature, 22 µVRMS output noise (100 Hz–100 kHz), and 175 mV typical dropout at 300 mA - enabling stable power in space-constrained battery-powered systems such as GPS modules and Bluetooth handsets.
For engineers reviewing the NCP717AMX150TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 25 µA quiescent current at no-load, XDFN-4 1.0×1.0 mm package, EN-controlled shutdown with <1 µA shutdown current, and guaranteed stability with 1 µF ceramic output capacitor.
Technical Context
The NCP717AMX150TCG integrates a PMOS pass transistor with adaptive quiescent current control to maintain ultra-low IQ across input voltage (1.8–5.5 V) and temperature (−40°C to +125°C). Its internal bandgap reference and error amplifier deliver tight regulation, while the dedicated EN pin enables logic-level ON/OFF control and activates a 1.2 kΩ active discharge path when disabled.
Thermal shutdown (160°C typical) and current limiting (379 mA typ.) are embedded for robust operation. The device achieves 70 dB PSRR at 1 kHz and requires no minimum ESR on the output capacitor - supporting compact, high-reliability designs where low noise and fast transient response are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% over full load/line/temperature range - ensures consistent core voltage for 1.5 V logic rails. |
| Max Output Current | 300 mA continuous - supports moderate-power RF ICs and microcontrollers in handheld devices. |
| Dropout Voltage | 175 mV typical at 300 mA - allows operation down to VIN = 1.675 V, extending battery life in single-cell Li-ion or Li-poly systems. |
| Quiescent Current | 25 µA typical at no-load - minimizes standby power loss in always-on sensor nodes and wearables. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz) - meets stringent noise requirements for ADC references and RF front-end biasing. |
| PSRR | 70 dB at 1 kHz - suppresses ripple from noisy switching supplies feeding intermediate LDO stages. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V GPIO without level-shifting. |
| Active Discharge | 1.2 kΩ pull-down on OUT when EN < 0.4 V - ensures rapid, controlled output discharge for sequencing-critical applications. |
Pinout & Package
Package: XDFN-4 (1.0 mm × 1.0 mm, 0.65 mm pitch), Case 711AJ, Pb-free, with exposed thermal pad (EPAD) connected to GND for enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output voltage node | Delivers stable 1.5 V; requires ≥1 µF ceramic capacitor to GND for stability and transient response. |
| 2 - GND | Power ground reference | Primary return path; EPAD must be soldered directly to GND plane for thermal and electrical integrity. |
| 3 - EN | Logic-enable control input | Drives >0.9 V to enable regulator; <0.4 V to disable and activate 1.2 kΩ output discharge. |
| 4 - IN | Input supply connection | Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor close to pin to suppress input ripple and transients. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 25 µA typ. at no-load - extends battery runtime in always-on IoT edge sensors and wearable health monitors. |
| Low-noise regulation | 22 µVRMS output noise - eliminates audible noise and preserves signal integrity in precision analog front-ends. |
| Active output discharge | Integrated 1.2 kΩ discharge path - prevents floating outputs during power-down, ensuring clean system reset and sequencing. |
| Stable with minimal capacitance | Guaranteed stability with 1 µF ceramic COUT - reduces BOM count and PCB area vs. legacy LDOs requiring 10+ µF tantalum. |
| Robust protection suite | Thermal shutdown (160°C), current limit (379 mA), and short-circuit immunity - enables unattended operation in sealed industrial enclosures. |

|---|---|---|---|
| MCP1703T-1502E/MB | Fixed 1.5 V, 250 mA, 6 µA IQ, no active discharge, SOT-23-5 package | Lacks output discharge; lower current rating limits use in higher-power RF sections | Select when ultra-low IQ dominates over discharge requirement and current demand ≤250 mA |
| Torex XC6219B152MR-G | Fixed 1.5 V, 300 mA, 1.0 µA IQ, no active discharge, SOT-25 package | Lower IQ but no discharge; different pinout and thermal performance limits high-current density layouts | Prefer for ultra-long-life coin-cell applications where discharge is unnecessary and board space permits SOT-25 |

FAQ
What is the output voltage tolerance of the NCP717AMX150TCG over temperature and load?
The NCP717AMX150TCG maintains ±2% output voltage accuracy across −40°C to +125°C junction temperature, 0–300 mA load, and input voltage range (1.8 V to 5.5 V). This specification is verified per the Electrical Characteristics table in the official datasheet, with min/max values guaranteed over the full operating range - ensuring reliable 1.5 V rail stability for precision analog and digital circuits.
Does the NCP717AMX150TCG require an external resistor for active output discharge?
No, the NCP717AMX150TCG integrates a 1.2 kΩ active discharge transistor internally. When the EN pin is driven below 0.4 V, this path automatically pulls the OUT pin to GND - eliminating need for external components and simplifying layout. This feature is confirmed in the "PIN FUNCTION DESCRIPTION" and "APPLICATIONS INFORMATION" sections of the NCP717 datasheet.
Can the NCP717AMX150TCG operate with only a 1 µF output capacitor?
Yes, the NCP717AMX150TCG is explicitly characterized and guaranteed stable with a single 1 µF ceramic output capacitor (X5R/X7R), as stated in the Features list and Applications Information section. This eliminates reliance on larger, higher-ESR capacitors and reduces solution size - a key advantage over legacy LDOs requiring ≥10 µF.
What is the maximum input voltage rating for the NCP717AMX150TCG?
The absolute maximum input voltage for the NCP717AMX150TCG is 6 V, as specified in the Absolute Maximum Ratings table. However, the recommended operating input voltage range is 1.8 V to 5.5 V. Exceeding 6 V risks permanent damage, and operation above 5.5 V voids parametric guarantees - including dropout, PSRR, and thermal performance.
How does the EN pin behave when left floating?
The EN pin of the NCP717AMX150TCG includes an internal 180 nA pull-down current source, ensuring the device remains disabled if the pin is unconnected. This behavior is documented in the "Enable Operation" subsection of the Applications Information section - preventing unintended startup and enhancing system reliability in designs where EN control is optional.
