Product details
Overview
NCP4586SN30T1 from onsemi is a CMOS 150 mA low-dropout linear regulator with 3.0 V fixed output, ±1% accuracy at 25°C, 320 mV typical dropout at full load, and 80 dB PSRR at 1 kHz - designed for power-sensitive portable electronics requiring stable low-noise biasing.
For engineers reviewing the NCP4586SN30T1 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, package mapping to SOT-23-5, thermal performance data, enable polarity confirmation (active-high CE), and real-world use context for battery-powered audio and imaging subsystems.
Technical Context
The NCP4586SN30T1 implements a CMOS pass transistor architecture enabling ultra-low quiescent current (38–58 µA) and high PSRR without external compensation. Its internal voltage reference and error amplifier deliver tight regulation across −40°C to +85°C ambient.
This variant features active-high chip enable (CE), auto-discharge disabled, and operates within 1.7–6.5 V input range. It achieves stable regulation with only 470 nF ceramic capacitors on input and output - eliminating need for tantalum or large bulk capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±1% (at TJ = 25°C); ensures precise biasing for 3.0 V logic, sensors, and RF front-ends |
| Max Output Current | 150 mA continuous; supports moderate-power microcontrollers, audio codecs, and camera modules |
| Dropout Voltage | 320 mV typ. at 150 mA (for VOUT = 3.0 V); enables operation down to VIN = 3.32 V, critical for single-cell Li-ion systems |
| PSRR | 80 dB at 1 kHz; suppresses switching noise from DC-DC converters feeding the LDO input |
| Output Noise | 30 µVRMS (10 Hz–100 kHz); suitable for noise-sensitive analog circuits like ADC references and microphone preamps |
| Quiescent Current | 38–58 µA; extends battery life in always-on sensor nodes and standby modes |
| Enable Threshold | VCEH = 1.0 V min; compatible with 1.8 V and 3.3 V GPIO control without level-shifting |
Pinout & Package
Package: SOT-23-5 (Case 1212), Pb-free, 2.7 mm × 2.5 mm footprint with exposed pad for thermal relief.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Input supply connection | Accepts 1.7–6.5 V; requires local 470 nF ceramic decoupling |
| 2 - GND | Power ground reference | Must be low-impedance; ties to PCB ground plane under exposed pad |
| 3 - CE | Active-high enable input | Pulled high to VIN to activate; pulled low to disable (standby current ≤1 µA) |
| 4 - NC | No connection | Internally unconnected; must remain floating or grounded per layout best practice |
| 5 - VOUT | Regulated output | Delivers 3.0 V ±1%; requires 470 nF ceramic capacitor directly at pin |
Key Features
| Feature | Design Value |
|---|---|
| Stable with 0.47 µF ceramic caps | Eliminates need for costly/low-reliability tantalum capacitors; reduces BOM count and board area |
| Low noise (30 µVRMS) | Meets stringent analog supply requirements for precision ADCs and low-noise amplifiers |
| High PSRR (80 dB @ 1 kHz) | Rejects ripple from upstream switching regulators, enabling mixed-signal SoC power domains |
| Ultra-low IQ (38–58 µA) | Extends runtime in battery-operated devices with periodic wake-up cycles (e.g., IoT sensors) |
| Thermal shutdown & current foldback | Protects against overloads and PCB overheating without external circuitry |
Applications
| Portable Audio Devices | Digital Camera Modules |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | 100 mA max output; 6 µA IQ; no CE pin; SOT-23-3 package | Lacks enable control and current capability; suited only for ultra-low-power always-on rails | Select only if system requires sub-10 µA standby and no enable sequencing |
| Torex XC6206P302MR-G | 300 mA output; 1 µA IQ; CE pin active-low; SOT-25 package | Higher current and lower IQ, but CE polarity mismatch requires GPIO inversion or redesign | Choose when >150 mA load or <1 µA standby is mandatory, and CE logic can be adapted |
Compared with MCP1700T-3002E/TT and XC6206P302MR-G, the NCP4586SN30T1 uniquely balances 150 mA drive, active-high CE, 30 µVRMS noise, and SOT-23-5 compatibility - making it optimal for portable imaging and audio where noise, enable control, and footprint are co-constrained.

FAQ
What is the enable polarity of the NCP4586SN30T1?
The NCP4586SN30T1 uses an active-high enable (CE) pin: applying ≥1.0 V to CE activates regulation, while ≤0.4 V disables output and reduces quiescent current to ≤1 µA. This matches standard 1.8 V/3.3 V GPIO logic levels without external inverters.
Can the NCP4586SN30T1 operate with a 2.5 V input?
No - the NCP4586SN30T1 requires minimum input voltage of 1.7 V, but for 3.0 V output, VIN must exceed VOUT by at least the dropout voltage. At 150 mA, dropout is 320 mV typ., so VIN ≥ 3.32 V is required for full-load regulation. At 2.5 V input, output collapses below specification.
Which capacitor values are validated for stability with the NCP4586SN30T1?
The NCP4586SN30T1 is characterized and stable with 470 nF ceramic capacitors on both input (CIN) and output (COUT). Larger values improve transient response but are not required; tantalum capacitors are discouraged due to ESR-related instability risks.
Does the NCP4586SN30T1 include output auto-discharge?
No - the NCP4586SN30T1 is the "S" variant (SOT-23-5, active-high CE, no auto-discharge). Only the "D" suffix variants (e.g., NCP4586DSN30T1G) integrate an internal discharge FET between VOUT and GND for rapid output decay during disable.
What is the thermal resistance (RJA) of the NCP4586SN30T1 in its SOT-23-5 package?
The NCP4586SN30T1 in SOT-23-5 (Case 1212) has a junction-to-air thermal resistance of 238°C/W under standard JEDEC test conditions. Actual performance improves significantly with PCB copper pour under the exposed pad and thermal vias.
