Product details

Overview

NCP4586DMU25TCG from onsemi is a CMOS low-dropout linear regulator delivering 150 mA output with 2.5 V fixed output voltage, 320 mV typical dropout at full load, ±1% output accuracy (at TJ = 25°C), and 80 dB PSRR at 1 kHz - designed for space-constrained battery-powered portable electronics requiring stable, low-noise power.

For engineers reviewing the NCP4586DMU25TCG datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, package-specific pin mapping, real-world application scenarios, and validated alternative options for low-noise LDO selection in high-density PCB designs.

Technical Context

The NCP4586DMU25TCG implements a CMOS-based LDO architecture with internal reference, error amplifier, and pass transistor - optimized for ultra-low quiescent current (38–58 µA) and fast transient response. It features active-high enable logic and supports stable operation with only 0.47 µF ceramic output capacitance.

This UDFN4 variant operates across 1.7–6.5 V input range, maintains ±1% output accuracy over −40°C to +85°C ambient, and achieves 30 µV_RMS output noise (10 Hz–100 kHz) - making it suitable for noise-sensitive analog and RF subsystems where supply ripple must be tightly controlled.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 2.5 V - eliminates external feedback network; enables single-component replacement in 2.5 V rail designs.
Max Output Current	150 mA - sufficient for powering microcontrollers, sensors, and low-power logic without thermal derating in UDFN4 package.
Dropout Voltage	320 mV typ. at 150 mA - allows regulation from 2.82 V input down to 2.5 V output, extending battery runtime in single-cell Li-ion or alkaline systems.
PSRR	80 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters, critical for ADC reference and audio codec supplies.
Output Noise	30 µV_RMS (10 Hz–100 kHz) - meets low-noise requirements for precision analog front-ends and RF biasing applications.
Quiescent Current	38–58 µA - minimizes standby power loss in always-on sensor nodes and IoT edge devices.
Enable Polarity	Active-high CE - simplifies control interface with standard GPIOs; internal pull-down ensures default disable state.

Pinout & Package

Package: 1.0 mm × 1.0 mm, 0.65 mm pitch UDFN4 (Case 517BR), Pb-free, wettable flank capable - optimized for automated optical inspection and high-density routing.

Pin/Terminal	Circuit Role	Design Meaning
VIN	Input supply connection	Accepts 1.7–6.5 V; requires local 470 nF ceramic decoupling to minimize line transients and EMI coupling.
GND	Power ground reference	Must be connected to low-impedance PCB ground plane; shared return path for VIN and VOUT capacitors.
CE	Chip enable input	Active-high logic control (V_CEH ≥ 1.0 V); internal pull-down ensures safe power-down when unconnected.
VOUT	Regulated output	Delivers stable 2.5 V ±1%; requires 470 nF ceramic capacitor placed adjacent to pin for stability and transient response.

Key Features

Feature	Design Value
Ultra-low noise output	30 µV_RMS (10 Hz–100 kHz) - preserves signal integrity in precision analog circuits without additional filtering.
Stable with minimal capacitance	0.47 µF ceramic output capacitor - reduces BOM count and board area vs. traditional LDOs requiring ≥2.2 µF.
Low dropout performance	320 mV typ. at 150 mA - enables efficient operation from partially discharged batteries in portable equipment.
High PSRR at audio frequencies	80 dB at 1 kHz - effectively isolates sensitive loads from DC-DC converter ripple and digital switching noise.
Thermal protection	Current fold-back limiting - prevents thermal runaway during sustained overload or short-circuit conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-noise LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1700T-2502E/TT	250 mA max output; 6 µA quiescent current; 1.6 V min input; no enable pin	Lacks CE control and higher noise (90 µV_RMS) - unsuitable for dynamic enable/disable or precision analog rails	Choose only if ultra-low IQ is primary requirement and enable functionality is unnecessary.
Torex XC6206P252MR-G	150 mA max; 1.0 µA IQ; 2.0 V min input; SOT-23-3 package; no enable	No enable function; smaller footprint but no CE control or auto-discharge capability	Select when board space is critical and system-level power sequencing is handled externally.

FAQ

What is the output voltage tolerance of the NCP4586DMU25TCG over temperature?

The NCP4586DMU25TCG maintains ±1.5% output voltage accuracy across −40°C to +85°C ambient temperature for V_OUT > 2 V. At 25°C, tolerance tightens to ±1.0%, and output voltage temperature coefficient is ±20 ppm/°C - ensuring stable 2.5 V regulation in thermally varying environments like outdoor wearables or industrial handhelds.

Does the NCP4586DMU25TCG require an external capacitor for stability?

Yes - the NCP4586DMU25TCG requires a minimum 0.47 µF ceramic capacitor on the VOUT pin, placed as close as possible to the device. This value is confirmed in the Electrical Characteristics table and Typical Application Schematic (Figure 42). Larger values improve transient response but are not required for basic stability.

What is the maximum input voltage rating for the NCP4586DMU25TCG?

The absolute maximum input voltage for the NCP4586DMU25TCG is 7 V, per Absolute Maximum Ratings. However, recommended operating input voltage is 1.7 V to 6.5 V. Exceeding 6.5 V may cause reliability degradation even if below 7 V, and thermal limits must be observed based on power dissipation in the UDFN4 package.

Is the NCP4586DMU25TCG pin-compatible with other variants in the NCP4586 family?

Yes - all NCP4586 UDFN4 variants (e.g., NCP4586DMU12TCG, NCP4586DMU33TCG) share identical 4-pin UDFN4 pinout and footprint. Only the marked output voltage differs; no PCB redesign is needed when substituting between fixed-output versions in the same package.

How does the enable function behave on the NCP4586DMU25TCG?

The NCP4586DMU25TCG uses active-high enable logic: VOUT regulates when CE ≥ 1.0 V (typical threshold), and shuts down when CE < 0.4 V. An internal pull-down current source (0.4 µA) ensures default OFF state if CE is left floating - eliminating need for external pull-down resistors in most implementations.
