Product details
Overview
NCP4588DMX10TCG from onsemi is a 200 mA, 1.0 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 70 dB PSRR at 1 kHz - designed for space-constrained battery-powered imaging and portable communication systems.
For engineers reviewing the NCP4588DMX10TCG datasheet, pinout, applications, or equivalent options, key selection criteria include output capacitor elimination capability, ultra-low IQ for standby operation, thermal performance in 1.2×1.2 mm XDFN, and auto-discharge functionality for rapid VOUT discharge during shutdown.
Technical Context
The NCP4588DMX10TCG implements a PMOS pass transistor architecture enabling stable regulation without an output capacitor, leveraging internal compensation to maintain phase margin across load and line variations. Its enable-controlled startup/shutdown sequence includes controlled turn-on and fast output discharge via integrated N-channel discharge switch.
It operates across 1.4 V to 5.25 V input range with ±1% initial output accuracy and 100 ppm/°C temperature coefficient, supporting low-noise (80 µVRMS) power delivery to noise-sensitive analog and RF circuitry in compact portable devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0 V ±1% at +25°C; ensures precise biasing for 1.0 V logic rails and low-voltage sensors |
| Max Output Current | 200 mA continuous; sufficient for powering microcontrollers, camera modules, and RF front-ends |
| Dropout Voltage | 270 mV at IOUT = 200 mA, VIN = 3.0 V; enables operation from single-cell Li-ion or 2×AA batteries down to ~1.27 V |
| Quiescent Current | <9.5 µA typical; minimizes battery drain in always-on monitoring or sleep-mode applications |
| PSRR | 70 dB at 1 kHz (VOUT ≤ 1.2 V); suppresses switching noise from DC-DC converters feeding the LDO input |
| Stability | Stable with zero output capacitance; eliminates BOM cost, board area, and reliability risk of external COUT |
| Enable Function | Active-high CE pin with 1.0 V threshold; supports system-level power sequencing and wake-up control |
| Auto-Discharge | Integrated N-ch discharge path (D-version only); pulls VOUT to GND within microseconds upon disable |
Pinout & Package
XDFN-6 package: 1.2 mm × 1.2 mm × 0.4 mm ultra-thin footprint with wettable flanks, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 1.4–5.25 V; requires 100 nF ceramic decoupling 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 | Chip enable control | Active-high logic input; internal pull-down ensures default-off state; tie to VIN if unused |
| VOUT | Regulated output | Delivers stable 1.0 V; supports capacitor-free operation or optional 0.1–10 µF ceramic for large load transients |
| NC | No connection | Pin 1 and Pin 5 are unconnected; must not be soldered or tied to any net |
Key Features
| Feature | Design Value |

| Capacitor-free stability | Eliminates mandatory output capacitor - reduces BOM count, PCB area, and failure modes in harsh environments |
| Ultra-low quiescent current | 9.5 µA typical enables >1-year battery life in intermittent-sensing IoT nodes powered by coin cells |
| Fast auto-discharge | D-version integrates dedicated discharge FET; discharges VOUT to <100 mV in <100 µs after CE deactivation |
| High PSRR at low frequencies | 70 dB @ 1 kHz improves immunity to noise from buck converter ripple and digital switching aggressors |
| Wide input voltage range | 1.4–5.25 V supports direct connection to single-cell Li-ion (2.7–4.2 V), NiMH, or USB-supplied systems |
| Precision output accuracy | ±1% over temperature ensures reliable operation of 1.0 V I/O domains and ADC references without calibration |

FAQ
Does the NCP4588DMX10TCG require an output capacitor to operate stably?
No, the NCP4588DMX10TCG is specifically designed for capacitor-free operation due to its internally compensated PMOS architecture. Stability is guaranteed from 0 to 200 mA load without any output capacitor. An optional 0.1–10 µF ceramic capacitor may be added to improve large-signal transient response, but it is not required for loop stability. This feature directly reduces bill-of-materials cost and PCB real estate in the NCP4588DMX10TCG design.
What is the purpose of the NC pins on the NCP4588DMX10TCG XDFN-6 package?
The NCP4588DMX10TCG XDFN-6 package has two NC (No Connection) terminals - Pin 1 and Pin 5 - which are electrically isolated and not bonded internally. These pins must remain unconnected in the PCB layout and should not be soldered to traces or ground planes. Their presence accommodates package standardization across the NCP4588 family and ensures mechanical compatibility; routing or terminating them would violate the device's validated thermal and electrical performance specifications for the NCP4588DMX10TCG.
How does the auto-discharge function work in the NCP4588DMX10TCG?
The NCP4588DMX10TCG (D-version) integrates an N-channel MOSFET between VOUT and GND that activates automatically when the CE pin is driven low. This discharge path pulls VOUT to GND within <100 µs, preventing residual voltage from interfering with downstream logic states or causing latch-up in powered-down subsystems. Unlike external discharge circuits, this function requires no additional components and is fully synchronized with the enable control - a key differentiator of the NCP4588DMX10TCG versus standard LDOs.
Can the NCP4588DMX10TCG be used with input voltages below 1.4 V?
No, the NCP4588DMX10TCG has a specified minimum input voltage of 1.4 V per its Absolute Maximum Ratings and Electrical Characteristics tables. Operation below 1.4 V may result in loss of regulation, increased dropout, or undefined behavior. For applications requiring lower VIN (e.g., deeply discharged Li-ion), the NCP4588DMX10TCG must be paired with a pre-regulator or selected only where input remains ≥1.4 V across the full battery discharge curve.
What is the thermal resistance (RJA) of the NCP4588DMX10TCG in its XDFN-6 package?
The NCP4588DMX10TCG in XDFN-6 package has a junction-to-air thermal resistance (RJA) of 250°C/W under standard JEDEC test conditions (1s2 pad, 1 oz copper). This value assumes a minimal 10 mm2 copper pour under the exposed pad. Actual RJA improves significantly with larger thermal pads, internal ground planes, and vias - enabling the NCP4588DMX10TCG to sustain 200 mA loads at ambient temperatures up to 85°C when properly laid out.
