Product details
Overview
NCP4586DMU30TCG from onsemi is a CMOS low-dropout linear regulator delivering 150 mA output with 3.0 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 - designed for power-sensitive portable electronics requiring stable, low-noise biasing.
For engineers reviewing the NCP4586DMU30TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its UDFN4 1.0×1.0 mm package, enable-high logic, auto-discharge capability, compatibility with 0.47 µF ceramic output capacitors, and operation across −40°C to +85°C ambient.
Technical Context
The NCP4586DMU30TCG implements a CMOS-based LDO architecture with internal reference, error amplifier, and pass transistor - optimized for low quiescent current (38–58 µA) and high ripple rejection. Its enable-high control pin activates regulation when pulled above 1.0 V, while the integrated auto-discharge transistor rapidly sinks output capacitance during shutdown.
Stability is ensured with ≥0.47 µF ceramic output capacitance and ESR < 100 mΩ; thermal protection limits junction temperature to +150°C. The device operates across 1.7–6.5 V input range and maintains ±1% output accuracy over temperature (−40°C to +85°C) for 3.0 V nominal output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±1% (at TJ = 25°C, VIN ≥ 4.0 V), enabling precise biasing of 3.0 V logic and analog circuits without external feedback. |
| Max Output Current | 150 mA continuous - sufficient for powering microcontrollers, sensors, and RF front-ends in compact portable systems. |
| Dropout Voltage | 320 mV typical at 150 mA (for VOUT = 3.0 V), allowing operation down to VIN = 3.32 V - critical for battery-powered devices near end-of-life. |
| PSRR | 80 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters, preserving signal integrity in audio and sensor signal chains. |
| Output Noise | 30 µVRMS (10 Hz–100 kHz) - supports low-noise analog circuitry such as ADC references and precision amplifiers. |
| Quiescent Current | 38–58 µA - minimizes standby power loss in always-on subsystems like real-time clocks or wake-up monitors. |
| Enable Threshold | VCEH = 1.0 V min - compatible with 1.8 V and 3.3 V GPIOs for reliable digital control without level-shifting. |
Pinout & Package
Package: UDFN4 (1.0 mm × 1.0 mm, 0.65 mm pitch, exposed thermal pad), Pb-free, moisture sensitivity level 1 (MSL1).
| 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 transient stability. |
| GND | Ground reference | Common return path for input/output currents and internal circuitry; must be connected to low-impedance PCB ground plane. |
| CE | Enable control (active-high) | Regulator enabled when CE ≥ 1.0 V; internal pull-down ensures default-off state if left floating - simplifies power sequencing. |
| VOUT | Regulated output | Delivers stable 3.0 V ±1%; supports ≥0.47 µF ceramic output capacitor; includes auto-discharge transistor for fast VOUT decay on disable. |
| NC | No connection | Unbonded terminal - must remain unconnected; no routing or soldering required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 320 mV typ. at 150 mA enables extended battery runtime in single-cell Li-ion (3.0–4.2 V) and 3.3 V system rails. |
| Low-noise regulation | 30 µVRMS output noise (10 Hz–100 kHz) eliminates need for post-LDO filtering in sensitive analog signal paths. |
| Auto-output discharge | Integrated N-channel discharge switch pulls VOUT to GND within milliseconds of CE deactivation - prevents residual voltage from interfering with downstream logic states. |
| Capacitor-stable design | Stable with ≥0.47 µF ceramic output capacitors (ESR < 100 mΩ), reducing BOM count and PCB area vs. tantalum-dependent LDOs. |
| Wide input range | 1.7–6.5 V operation supports diverse sources: single Li-ion, two alkaline cells, USB VBUS, or intermediate DC/DC outputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | 300 mA output, 6 µA quiescent current, no auto-discharge, SOT-23-3 package | Lacks active output discharge; requires external circuitry for fast VOUT decay; higher max current but larger footprint | Select when ultra-low IQ dominates requirements and auto-discharge is unnecessary. |
| Torex XC6206P302MR-G | 150 mA output, 1.0 µA standby current, no enable pin, SOT-25 package | Always-on operation only; no digital control; lower IQ but no power sequencing capability | Select for simple, cost-sensitive always-on rails where enable control and discharge are not needed. |

FAQ
What is the maximum input voltage rating for the NCP4586DMU30TCG?
The NCP4586DMU30TCG has an absolute maximum input voltage rating of 7 V. Operation beyond this value risks permanent damage. For reliable long-term use, the recommended operating input range is 1.7 V to 6.5 V - ensuring safe margin below the absolute limit while supporting common battery and DC/DC source voltages.
Does the NCP4586DMU30TCG require an external resistor network to set output voltage?
No, the NCP4586DMU30TCG is a fixed-output regulator with factory-trimmed 3.0 V output. It does not use external feedback resistors. This eliminates component count, layout sensitivity, and drift-related inaccuracies - delivering ±1% output voltage accuracy over temperature without external components.
Can the NCP4586DMU30TCG operate with a 0.22 µF ceramic output capacitor?
No. The NCP4586DMU30TCG requires a minimum 0.47 µF ceramic output capacitor for guaranteed stability, as specified in the datasheet. Using 0.22 µF may cause oscillation or poor transient response. Always place the capacitor within 2 mm of VOUT and GND pins with low-inductance traces.
What is the purpose of the NC pin on the NCP4586DMU30TCG UDFN4 package?
The NC (No Connection) pin on the NCP4586DMU30TCG is an unconnected, unbonded terminal. It serves no electrical function and must remain unconnected - neither routed nor soldered. Leaving it floating poses no risk; connecting it to GND or any other net may compromise thermal performance or reliability.
How does the auto-discharge feature behave during shutdown of the NCP4586DMU30TCG?
When the CE pin is driven low (disable state), the NCP4586DMU30TCG activates an internal N-channel transistor between VOUT and GND. This discharges the output capacitor rapidly - typically reducing VOUT to < 100 mV within 1–2 ms depending on capacitance and load - preventing unintended operation of downstream circuitry during power-down sequences.
