Product details
Overview
NCP4588DMX15TCG from onsemi is a 200 mA, 1.5 V fixed-output CMOS LDO linear voltage regulator in XDFN-6 package, featuring capacitor-free stability, 270 mV dropout at 200 mA, 9.5 µA quiescent current, and 65 dB PSRR at 1 kHz - deployed in portable cameras and battery-powered communication equipment where board space and low power are critical.
For engineers reviewing the NCP4588DMX15TCG datasheet, pinout, applications, or equivalent options, key selection criteria include output capacitor elimination capability, ultra-low IQ for standby operation, auto-discharge functionality, thermal performance in 1.2×1.2 mm XDFN, and compatibility with 1.4–5.25 V input rails in space-constrained embedded systems.
Technical Context
The NCP4588DMX15TCG implements a CMOS pass element with internal bandgap reference and error amplifier to regulate 1.5 V output across 1.4–5.25 V input. Its architecture enables stable operation without an output capacitor due to inherent phase margin design and low output impedance.
It integrates active chip enable (CE) logic with 1.0 V high-threshold and 0.4 V low-threshold, plus an internal N-channel discharge transistor activated during shutdown - a feature exclusive to the "D" variant denoted in the part number suffix and confirmed in the Ordering Information table on page 14.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±1% over −40°C to +85°C - ensures precise rail generation for 1.5 V logic or analog circuitry without external feedback. |
| Max Output Current | 200 mA continuous - supports moderate-power peripherals like camera sensors or RF front-end ICs. |
| Dropout Voltage | 270 mV at IOUT = 200 mA, VIN = 3.0 V - enables regulation from 1.77 V input, extending battery runtime in single-cell Li-ion or alkaline systems. |
| Quiescent Current | 9.5 µA typical - minimizes no-load power loss, critical for always-on subsystems in portable devices. |
| PSRR | 65 dB at 1 kHz (1.2 V < VOUT < 2.2 V) - suppresses switching noise from DC-DC converters feeding the LDO input. |
| Stability | Stable with 0 µF output capacitance - eliminates BOM cost, PCB area, and reliability risk associated with external ceramic capacitors. |
| Auto-Discharge | Integrated N-ch discharge path from VOUT to GND when CE = low - reduces residual output voltage within microseconds, preventing latch-up in downstream logic. |
Pinout & Package
XDFN-6 (Case 711AA), 1.2 mm × 1.2 mm × 0.4 mm, Pb-free, wettable flank compatible. Thermal resistance RJA = 250°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 1.4–5.25 V; requires 100 nF ceramic decoupling capacitor placed adjacent to pin. |
| GND | Power ground reference | Low-impedance return path; must be connected to solid ground plane for PSRR and thermal performance. |
| CE | Active-high enable control | Logic high ≥1.0 V enables regulation; internal pull-down ensures default-off state if left floating. |
| VOUT | Regulated output terminal | Delivers 1.5 V ±1%; includes integrated discharge FET (D-version only) for rapid VOUT collapse on disable. |
| NC | No connection | Two pins (1 and 5) are internally unconnected - must remain unconnected on PCB; not for grounding or routing. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitor-free operation | Eliminates mandatory output capacitor, reducing component count, cost, and PCB footprint while improving reliability in shock/vibe environments. |
| Ultra-low quiescent current | 9.5 µA typical enables >1-year battery life in coin-cell-powered IoT sensors with periodic wake-up cycles. |
| Integrated output discharge | D-version's internal N-ch FET discharges VOUT to <100 mV within 100 µs of CE deactivation, preventing back-powering of upstream circuits. |
| High PSRR at 1 kHz | 65 dB suppression of 1 kHz ripple allows clean 1.5 V supply even when powered from noisy buck converter outputs. |
| Wide input voltage range | 1.4–5.25 V operation supports direct connection to single Li-ion (2.7–4.2 V), 3.3 V rails, or multi-cell alkaline stacks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/TT | 250 mA rated, 6 µA IQ, no auto-discharge, SOT-23-3 package | Lacks VOUT discharge; requires external pulldown for fast turn-off; larger footprint than XDFN-6 | Select when lowest possible IQ is priority and discharge is handled externally. |
| Torex XC6206P152MR-G | 150 mA rated, 1 µA IQ, no CE pin, SOT-25 package | Fixed-enable only; no shutdown control; lower current limit restricts use with higher-load peripherals | Select for always-on, ultra-low-power micro-sensors where enable control is unnecessary. |
Compared with MCP1700T-1502E/TT and XC6206P152MR-G, the NCP4588DMX15TCG uniquely combines 200 mA drive, 9.5 µA IQ, active CE control, and integrated auto-discharge in a 1.2×1.2 mm XDFN - making it optimal for space-constrained, battery-operated systems requiring deterministic power sequencing.

FAQ
What is the output voltage tolerance of the NCP4588DMX15TCG over temperature?
The NCP4588DMX15TCG maintains 1.5 V output within ±1.5% over −40°C to +85°C ambient temperature, as specified in the ELECTRICAL CHARACTERISTICS table on page 3: for VOUT ≤ 2.0 V, min/max deviation is ±30 mV across the full temperature range. This ensures reliable operation of 1.5 V logic interfaces without external trimming.
Does the NCP4588DMX15TCG require an output capacitor for stability?
No, the NCP4588DMX15TCG is explicitly designed to be stable with 0 µF output capacitance, as stated in the device description on page 1 and confirmed in Figure 21–23 showing PSRR performance with COUT = 0 F. An optional 0.1–10 µF ceramic capacitor may be added only to improve large-signal load transient response.
What is the purpose of the NC pins on the NCP4588DMX15TCG XDFN-6 package?
The NCP4588DMX15TCG XDFN-6 package has two NC (no connection) pins - pins 1 and 5 per the PIN FUNCTION DESCRIPTION table on page 2. These pins are electrically unconnected internally and must remain unconnected on the PCB; they are not intended for grounding, thermal relief, or signal routing.
How does the auto-discharge function operate in the NCP4588DMX15TCG?
The NCP4588DMX15TCG (D-version) activates its internal N-channel discharge transistor between VOUT and GND when the CE pin is driven low. As shown in Figure 42–44, this pulls VOUT to <100 mV within ~20 µs, preventing back-powering of upstream circuitry and ensuring safe power-down sequencing in multi-rail systems.
What is the maximum power dissipation of the NCP4588DMX15TCG in its XDFN package?
The NCP4588DMX15TCG in XDFN-6 package has a maximum power dissipation (PD) rating of 400 mW, as listed in the ABSOLUTE MAXIMUM RATINGS table on page 2. At 200 mA load and 270 mV dropout, power dissipation is 54 mW - well within limits, but thermal design must consider RJA = 250°C/W and PCB copper area for sustained operation near ambient limits.
