Product details
Overview
NCP4586DSQ50T1G from onsemi is a CMOS low-dropout linear regulator delivering 150 mA output with 5.0 V fixed output voltage, ±1% accuracy at 25°C, 320 mV typical dropout at full load, and 80 dB PSRR at 1 kHz - designed for stable power in space-constrained portable electronics.
For engineers reviewing the NCP4586DSQ50T1G datasheet, pinout, applications, or equivalent options, this page provides verified technical context, package-specific pin mapping, real-world application roles, and validated alternative options for battery-powered and noise-sensitive systems.
Technical Context
The NCP4586DSQ50T1G implements a CMOS-based LDO architecture with internal reference, error amplifier, and pass transistor optimized for low-noise operation and fast transient response. It features an enable-high control logic (CE active high) and integrated auto-discharge circuitry that actively pulls down VOUT during shutdown to rapidly dissipate stored charge.
Designed for ultra-low quiescent current (38–58 µA active, ≤1 µA standby), it operates across 1.7–6.5 V input while maintaining regulation down to 7 V absolute max input. Its stability with 0.47 µF ceramic output capacitors eliminates need for large bulk capacitance, supporting compact PCB layouts in high-density applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±1% (at TJ = 25°C, VOUT > 2 V); ensures precise rail generation for USB-peripheral interfaces and microcontroller I/O domains. |
| Max Output Current | 150 mA continuous; sufficient to power single-core MCUs, sensors, or RF transceivers without thermal derating under typical ambient conditions. |
| Dropout Voltage | 320 mV typical at 150 mA (for 5.0 V version); enables regulation from 5.32 V input - critical for single-cell Li-ion or multi-cell alkaline systems. |
| PSRR | 80 dB at 1 kHz; suppresses switching noise from upstream DC-DC converters, preserving signal integrity in ADC reference or audio bias rails. |
| Output Noise | 30 µVRMS (10 Hz–100 kHz); supports low-noise analog circuits including precision op-amps and RF front-end biasing. |
| Quiescent Current | 38–58 µA; minimizes battery drain in always-on monitoring functions like real-time clocks or wake-on-event sensors. |
| Enable Polarity | Active-high CE pin (H-version); simplifies interface with GPIOs lacking open-drain capability and avoids external pull-up resistors in most host designs. |
Pinout & Package
Package: SC−82AB (Case 419C), 4-pin surface-mount, 1.8 × 1.15 mm footprint, 0.65 mm pitch, Pb-free, moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SC−82AB) | VIN | Main input supply connection; requires local 470 nF ceramic decoupling to minimize line impedance and improve transient immunity. |
| 2 (SC−82AB) | GND | Power ground reference; must be connected to low-impedance PCB plane to maintain PSRR and prevent oscillation. |
| 3 (SC−82AB) | CE | Enable input (active high); internally pulled down; drives regulator ON when ≥1.0 V applied, OFF when ≤0.4 V. |
| 4 (SC−82AB) | VOUT | Regulated 5.0 V output; connects to load and 470 nF ceramic capacitor; auto-discharge path activates during disable to clear residual charge. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 30 µVRMS output noise enables clean power for analog sensor signal chains and RF bias networks without additional filtering. |
| Auto-discharge function | Integrated N-channel discharge transistor rapidly depletes output capacitance during shutdown - essential for safe hot-swap or reset sequencing. |
| Stable with 0.47 µF ceramic | Eliminates need for tantalum or electrolytic capacitors, reducing BOM cost, board area, and long-term reliability risk from ESR drift. |
| High PSRR at 1 kHz | 80 dB rejection of ripple from switching regulators allows co-location with DC-DC stages in compact portable designs. |
| Low dropout at full load | 320 mV dropout preserves headroom in battery-powered systems where input voltage sags below 5.5 V during discharge cycles. |
Applications
| USB Peripheral Power Supply | Digital Camera Sensor Bias |
|---|---|
|

IC Role / Device Role / Timing Role: Main system LDO delivering consistent voltage despite battery voltage decay from 4.2 V to 3.0 V. Use Value: 320 mV dropout enables >150 mA delivery down to 5.32 V input - extends usable runtime from single-cell Li-ion packs. |
Use Scenario: Powering ARM Cortex-M0+/M4 cores and associated peripherals in battery-operated IoT edge nodes requiring low sleep current. IC Role / Device Role / Timing Role: Always-on LDO supplying MCU VDD_IO and analog subsystems with controlled enable sequencing. Use Value: ≤1 µA standby current minimizes quiescent drain during deep-sleep modes; active 38–58 µA IQ supports frequent wake-up intervals without battery exhaustion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-5002E/TT | 500 mA rated, 6 µA IQ, no auto-discharge, SOT-23-3 package | Lacks active output discharge; requires external circuitry for safe reset in systems with hold-up capacitance. | Choose when higher current headroom is needed and auto-discharge is not required; verify thermal performance at 150 mA in SOT-23-3. |
| TZB5005002R | 500 mA rated, 2.5 µA IQ, 200 mV dropout at 150 mA, SC-70-5 package | Lower dropout but no integrated discharge transistor; tighter 0.5% initial accuracy. | Prefer for ultra-low-power designs where <1 µA standby is mandatory and external discharge can be implemented. |
Compared with MCP1700T-5002E/TT and TZB5005002R, the NCP4586DSQ50T1G uniquely combines 5.0 V fixed output, auto-discharge, SC−82AB compactness, and verified 30 µVRMS noise - making it optimal for portable systems requiring safe, quiet, and space-efficient 5 V regulation.

What is the maximum input voltage rating for the NCP4586DSQ50T1G?
The NCP4586DSQ50T1G has an absolute maximum input voltage rating of 7 V, as specified in the Absolute Maximum Ratings table. Operation above this limit risks permanent device damage. For reliable long-term use, the recommended operating input range is 1.7 V to 6.5 V - ensuring proper regulation and thermal safety under all load and temperature conditions for the NCP4586DSQ50T1G.
Does the NCP4586DSQ50T1G include output auto-discharge functionality?
Yes, the NCP4586DSQ50T1G includes integrated auto-discharge functionality. As indicated by the "D" suffix in its part number and confirmed in the Application Information section, it contains an internal N-channel transistor between VOUT and GND that activates during disable mode to rapidly discharge the output capacitor - a key feature for safe reset sequencing and preventing residual voltage in portable systems.
What package type is used for the NCP4586DSQ50T1G?
The NCP4586DSQ50T1G uses the SC−82AB package (Case 419C), a 4-pin surface-mount outline measuring 1.8 × 1.15 mm with 0.65 mm pitch. This compact, Pb-free package is optimized for high-density PCB layouts and is distinct from the UDFN4 and SOT-23-5 variants offered in the same NCP4586 family.
What is the typical dropout voltage of the NCP4586DSQ50T1G at full load?
The typical dropout voltage of the NCP4586DSQ50T1G is 320 mV at 150 mA output current and 25°C junction temperature, as documented in the Electrical Characteristics table. This value applies specifically to the 5.0 V output variant and enables stable regulation from inputs as low as 5.32 V - critical for extending runtime in single-cell Li-ion and multi-cell alkaline applications.
Is the NCP4586DSQ50T1G compatible with ceramic output capacitors?
Yes, the NCP4586DSQ50T1G is explicitly characterized and guaranteed stable with a minimum 0.47 µF ceramic output capacitor, as stated in the Features list and Application Information section. No ESR requirements or damping resistors are needed, enabling small-footprint, high-reliability designs without tantalum or aluminum electrolytic components.
