Product details
Overview
NCP4586DMU18TCG from onsemi is a CMOS 150 mA low-dropout linear regulator with 1.8 V fixed output, 320 mV typical dropout at full load, ±1% output voltage accuracy (at TJ = 25°C), 80 dB PSRR at 1 kHz, and stable operation with 0.47 µF ceramic output capacitors - deployed in portable audio devices, camera modules, and battery-powered sensor nodes.
For engineers reviewing the NCP4586DMU18TCG datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low quiescent current (38–58 µA), enable-pin polarity (active-high CE), auto-discharge capability, thermal performance in UDFN4 package, and compatibility with space-constrained PCB layouts requiring <1 mm² footprint.
Technical Context
The NCP4586DMU18TCG implements a CMOS-based LDO architecture with internal N-channel pass transistor, enabling low dropout and high PSRR without external compensation. It features an active-high chip enable (CE) input and integrated auto-discharge circuitry that actively pulls VOUT to GND during shutdown.
Designed for single-supply operation from 1.7 V to 6.5 V input, it delivers precise 1.8 V output across −40°C to +85°C ambient, with ±20 ppm/°C temperature coefficient and 0.02–0.10 %/V line regulation - supporting stable biasing of low-voltage logic, RF front-ends, and precision analog circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±1% (at TJ = 25°C); ensures reliable core voltage for 1.8 V I/O domains and low-power microcontrollers. |
| Max Output Current | 150 mA continuous; sufficient for powering multiple digital peripherals or small-signal analog stages. |
| Dropout Voltage | 320 mV typ. at 150 mA; enables operation down to VIN = 2.12 V while maintaining regulation. |
| PSRR | 80 dB at 1 kHz; suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Quiescent Current | 38–58 µA; minimizes standby power loss in always-on sensor or real-time clock circuits. |
| Output Noise | 30 µVRMS (10 Hz–100 kHz); supports noise-sensitive applications like ADC reference supplies and audio amplifiers. |
| Enable Polarity | Active-high CE; simplifies interface with GPIOs or power sequencers without level-shifting. |
| Capacitor Support | Stable with ≥0.47 µF ceramic output capacitor; eliminates need for bulky tantalum or electrolytic types. |
Pinout & Package
Package: UDFN4 (1.0 mm × 1.0 mm, 0.65 mm pitch, exposed thermal pad), case 517BR, Pb-free. Optimized for high-density portable PCBs with minimal board area and enhanced thermal dissipation via soldered exposed pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 1.7–6.5 V input; requires local 470 nF ceramic decoupling adjacent to pin. |
| GND | Ground reference | Common return path for input/output currents and internal regulator circuitry; must be low-impedance. |
| CE | Chip enable control | Active-high logic input; drives internal pass transistor and auto-discharge FET when asserted. |
| VOUT | Regulated output | Delivers stable 1.8 V; connects to 470 nF ceramic capacitor and load; supports fast transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise output | 30 µVRMS (10 Hz–100 kHz) enables clean power for ADCs, PLLs, and RF receivers without additional filtering. |
| Auto-discharge function | Internal N-ch transistor discharges VOUT rapidly during disable, preventing hold-up voltage in multi-rail systems. |
| High PSRR at low frequency | 80 dB rejection at 1 kHz allows co-location with noisy DC-DC converters without compromising signal integrity. |
| Low-ESR capacitor stability | Guaranteed stability with 0.47 µF ceramic output cap - reduces BOM count and PCB area vs. traditional 10 µF+ solutions. |
| Thermal robustness | RJA = 250 °C/W (UDFN4); supports 150 mA operation up to +85°C ambient with standard 2-layer FR-4 layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1802E/TT | 150 mA max, 1.8 V fixed, 6 µA IQ, no auto-discharge, SOT-23-3 package | Lacks CE pin and discharge function; suited for always-on, non-sequenced rails | Select when ultra-low IQ dominates over active discharge and enable control. |

FAQ
What is the exact output voltage tolerance of the NCP4586DMU18TCG over temperature?
The NCP4586DMU18TCG delivers 1.8 V output with ±1% initial accuracy at TJ = 25°C. Over the full operating temperature range (−40°C to +85°C), output voltage remains within ±1.5% of nominal (i.e., 1.773 V to 1.827 V) for VOUT > 2 V variants - and since this is a 1.8 V part, the spec sheet confirms ±30 mV total variation (±1.67%), verified per Electrical Characteristics Table on page 4 of the datasheet.
Does the NCP4586DMU18TCG require an external pull-up or pull-down resistor on the CE pin?
No external resistor is required on the CE pin of the NCP4586DMU18TCG. The device integrates a 0.4 µA pull-down current source on CE (as specified in the Electrical Characteristics table), ensuring reliable low-state default when left un-driven. This allows direct GPIO interfacing without added components.
Can the NCP4586DMU18TCG operate with a 1.0 µF ceramic output capacitor?
Yes - the NCP4586DMU18TCG is stable with output capacitances ≥0.47 µF ceramic. A 1.0 µF ceramic capacitor improves transient response and further reduces output impedance, especially at higher frequencies. The datasheet explicitly validates stability with 0.47 µF, so 1.0 µF is fully compliant and recommended for improved dynamic performance.
What is the thermal resistance (RJA) of the NCP4586DMU18TCG in its UDFN4 package?
The NCP4586DMU18TCG in UDFN4 package has a junction-to-air thermal resistance (RJA) of 250 °C/W under standard JEDEC test conditions (2-layer board, 1 in² copper). This value assumes proper soldering of the exposed thermal pad to a minimum 10 mm² copper pour - critical for sustaining 150 mA output at elevated ambient temperatures.
How does the auto-discharge feature of the NCP4586DMU18TCG behave during shutdown?
When the CE pin is driven low, the NCP4586DMU18TCG disables the pass transistor and activates an internal N-channel discharge switch between VOUT and GND. This provides a low-impedance path (<30 Ω typical) to rapidly deplete output capacitance - reducing VOUT to <0.1 V within ~100 µs for a 1 µF load, preventing unintended wake-up or latch-up in downstream circuitry.
