Product details
Overview
NCP4586DMU12TCG from onsemi is a 150 mA, low-noise, low-dropout linear regulator with 1.2 V fixed output voltage, 320 mV typical dropout at full load, ±1% output accuracy (at VOUT > 2 V), and 80 dB PSRR at 1 kHz. It operates from 1.7 V to 6.5 V input and supports battery-powered portable electronics requiring stable, low-ripple power.
For engineers reviewing the NCP4586DMU12TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its UDFN4 1.0×1.0 mm package, enable-high logic, auto-discharge capability, and compatibility with 0.47 µF ceramic output capacitors - critical for space-constrained, low-power designs.
Technical Context
The NCP4586DMU12TCG implements a CMOS-based LDO architecture with internal N-channel pass transistor, enabling low quiescent current (38–58 µA) and fast transient response. Its enable-high control pin activates regulation when pulled high, while the integrated auto-discharge transistor rapidly bleeds output capacitance during shutdown.
Designed for high PSRR (80 dB @ 1 kHz) and ultra-low output noise (30 µVRMS, 10 Hz–100 kHz), it delivers clean power to noise-sensitive analog circuits and RF subsystems. Thermal performance is optimized for UDFN4 package with RJA = 250 °C/W, supporting continuous 150 mA operation within −40°C to +85°C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V - matches core voltage requirements of low-power microcontrollers and memory interfaces. |
| Max Output Current | 150 mA - sufficient for powering single-core MCUs, sensors, or RF transceivers in portable devices. |
| Dropout Voltage | 320 mV typ. at 150 mA - enables operation down to VIN = 1.52 V, extending battery runtime in Li-ion and coin-cell applications. |
| PSRR | 80 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Output Noise | 30 µVRMS (10 Hz–100 kHz) - ensures minimal interference in ADC references, audio codecs, and PLL power rails. |
| Quiescent Current | 38–58 µA - minimizes standby power loss in always-on sensor nodes and wearable electronics. |
| Input Voltage Range | 1.7 V to 6.5 V - accommodates single-cell Li-ion (2.7–4.2 V), alkaline (1.5 V × 2), and regulated 3.3/5 V system rails. |
Pinout & Package
Package: UDFN4 (1.0 mm × 1.0 mm, 0.65 mm pitch, Case 517BR), Pb-free, wettable flank capable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 1.7–6.5 V; requires 470 nF ceramic decoupling capacitor placed adjacent to pin for stability and line transient immunity. |
| GND | Ground reference | Common return path for input/output capacitors and load; must be low-impedance PCB plane to minimize noise coupling. |
| CE | Enable control (active-high) | Pull high ≥1.0 V to enable regulation; pull low ≤0.4 V to disable; internal pull-down current source (0.4 µA) ensures default-off state. |
| VOUT | Regulated output | Delivers stable 1.2 V ±1% (at 25°C); supports 0.47 µF ceramic output capacitor; includes auto-discharge transistor to rapidly discharge external capacitance on disable. |
| NC | No connection | Unbonded pad - must remain unconnected and may be left floating or tied to GND for thermal enhancement (per layout guidelines). |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 30 µVRMS output noise enables use in precision analog signal chains without additional filtering. |
| Auto-discharge function | Integrated N-ch transistor discharges VOUT capacitance quickly upon CE deactivation - critical for safe power sequencing in multi-rail systems. |
| Ultra-small footprint | UDFN4 1.0×1.0 mm package reduces PCB area by >60% vs. SOT-23-5, supporting high-density portable PCB layouts. |
| High PSRR at low frequency | 80 dB rejection at 1 kHz allows co-location with noisy digital supplies without compromising analog rail integrity. |
| Stable with minimal capacitance | Guaranteed stability with only 0.47 µF ceramic output capacitor - eliminates need for larger, costly tantalum or polymer types. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1202E/TT | 150 mA, 1.2 V fixed, 6 µA IQ, no auto-discharge, SOT-23-3 package | Lacks enable pin and discharge function; limited to always-on or simple ON/OFF control via VIN | Choose when ultra-low IQ dominates design priority and auto-discharge is unnecessary. |
| Torex XC6206P122MR-G | 150 mA, 1.2 V fixed, 1.0 µA IQ, no enable, SOT-25 package | No enable control or discharge; lower IQ but higher dropout (500 mV @ 150 mA) | Prefer for maintenance-free, non-sequenced applications where minimum standby power is critical. |
Compared with MCP1700T-1202E/TT and XC6206P122MR-G, the NCP4586DMU12TCG uniquely combines enable-high logic, auto-discharge, and 320 mV dropout in a 1.0×1.0 mm UDFN - making it optimal for compact, sequenced, battery-sensitive systems where rapid power-down and minimal board area are mandatory.

FAQ
What is the output voltage tolerance of the NCP4586DMU12TCG over temperature?
The NCP4586DMU12TCG maintains ±1.5% output voltage accuracy across −40°C to +85°C ambient temperature for VOUT > 2 V; for the 1.2 V version, total variation is ±30 mV over this range per datasheet Table 1. This ensures reliable operation in outdoor and industrial environments without external trimming.
Does the NCP4586DMU12TCG require an external resistor network for output voltage setting?
No - the NCP4586DMU12TCG is a fixed-output device with factory-trimmed 1.2 V regulation. It contains no feedback pins or external resistor connections; output voltage is set internally and cannot be adjusted. This simplifies layout and eliminates resistor tolerance errors.
Can the NCP4586DMU12TCG operate with a 1.0 µF ceramic output capacitor?
Yes - while the datasheet specifies stability with ≥0.47 µF, the NCP4586DMU12TCG remains stable with 1.0 µF ceramic output capacitors. Larger values improve load transient response and reduce output ripple, but do not affect phase margin or risk oscillation.
What is the maximum junction temperature rating for the NCP4586DMU12TCG?
The NCP4586DMU12TCG has a maximum junction temperature (TJ(MAX)) of +150°C. With its UDFN4 package RJA of 250°C/W, sustained 150 mA operation at 85°C ambient requires ≤260 mW power dissipation - achievable with VIN ≤ 2.9 V under worst-case dropout conditions.
Is the NCP4586DMU12TCG RoHS and REACH compliant?
Yes - the NCP4586DMU12TCG is a Pb-free device manufactured in compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Its marking "VA" and packaging code "UDFN4" confirm full environmental compliance per onsemi's material declarations.
