Product details
Overview
NCP4587DMX28TCG from onsemi is a 150 mA tri-mode CMOS LDO voltage regulator with auto-eco/fast/standby operation modes, 2.8 V fixed output, 120 mV typical dropout at 150 mA (VOUT ≥ 2.6 V), ±1% output accuracy (TJ = 25°C), and stable operation with ceramic capacitors. It serves as a low-noise, high-PSRR power supply for image sensors and portable camera modules.
For engineers reviewing the NCP4587DMX28TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 2.8 V fixed output, XDFN-6 1.2 × 1.2 mm ultra-thin package, tri-mode current optimization (1.0 µA low-power / 55 µA fast mode), 70 dB PSRR at 1 kHz, and integrated auto-discharge function.
Technical Context
The NCP4587DMX28TCG implements a CMOS-based pass transistor architecture with dual-mode control logic that switches between low-quiescent-current Eco mode (<2 mA load) and fast-response mode (>8 mA load), configurable via the AE pin. Its internal reference and error amplifier deliver tight line/load regulation (0.02%/V typ., ±1% VOUT accuracy).
It integrates fold-back current limiting, thermal shutdown, and an active output discharge transistor (D-version feature), enabling rapid VOUT collapse during disable. The device operates across 1.4–5.25 V input and maintains stability with ≥0.47 µF ceramic output capacitance without ESR requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V - eliminates external feedback network; supports standard I/O rail in imaging and sensor subsystems. |
| Max Output Current | 150 mA - sufficient for powering CMOS image sensors, analog front-ends, and low-power microcontrollers. |
| Dropout Voltage | 120 mV typ. at 150 mA (VOUT ≥ 2.6 V) - enables operation from single-cell Li-ion or 3.3 V rails with minimal headroom loss. |
| Quiescent Current | 1.0 µA in Low Power Mode - extends battery life in always-on camera standby states. |
| PSRR | 70 dB at 1 kHz (Fast Mode) - suppresses switching noise from adjacent DC-DC converters in compact portable designs. |
| Accuracy | ±1% at VOUT > 2 V, TJ = 25°C - ensures reliable logic-level compatibility and ADC reference stability. |
| Package | XDFN-6 (1.2 × 1.2 × 0.4 mm) - ultra-low profile for space-constrained camera modules and wearable optics. |
Pinout & Package
XDFN-6 package: 1.2 mm × 1.2 mm footprint, 0.4 mm height, wettable flank terminals, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 1.4–5.25 V; requires local 0.47 µF ceramic decoupling to minimize line transients. |
| GND | Power ground reference | Common return path for VIN, VOUT, CE, and AE; must be low-impedance for PSRR and noise immunity. |
| CE | Chip enable (active-high) | Pull-up to VIN if unused; enables full shutdown (0.1 µA standby) and controlled start-up sequencing. |
| VOUT | Regulated output | Delivers stable 2.8 V; includes integrated discharge FET (D-version) for rapid ramp-down when disabled. |
| AE | Auto Eco mode select | Low/floating = automatic tri-mode switching; high = permanent Fast Mode for consistent transient response. |
| NC | No connection | Terminal 5 is unconnected; must not be soldered or biased - no internal circuitry attached. |
Key Features
| Feature | Design Value |
|---|---|
| Tri-mode operation | Automatically transitions between 1.0 µA low-power, 55 µA fast, and 0.1 µA standby modes based on load current thresholds (1–8 mA). |
| Integrated output discharge | Active NMOS discharge path from VOUT to GND ensures <1 ms output collapse during disable - critical for system-level power sequencing. |
| Ceramic capacitor stability | Stable with ≥0.47 µF X5R/X7R ceramics; eliminates need for high-ESR tantalum or aluminum electrolytics in space-limited layouts. |
| High PSRR at 1 kHz | 70 dB attenuation of ripple/noise from upstream DC-DC converters - preserves signal integrity in analog sensor chains. |
| Ultra-thin XDFN package | 0.4 mm max height enables stacking under camera lenses or integration into sub-1 mm Z-height modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0528PDBVR | 200 mA rated, 25 µA IQ (no tri-mode), 170 mV dropout at 200 mA, SOT-23-5 package (2.9 × 1.6 mm). | Larger footprint, higher dropout, no auto-discharge - suitable where board area allows and discharge not required. | Select if higher output current margin is needed and tri-mode optimization is secondary. |
| MCP1700-2802E/TO | 250 mA rated, 1.6 µA IQ (fixed low-IQ), 600 mV dropout at 250 mA, TO-92 through-hole package. | Through-hole mounting, much larger size, significantly higher dropout - limited to non-portable, cost-sensitive designs. | Select only for legacy through-hole assembly or where ultra-low cost outweighs size/power penalties. |
Compared with TPS7A0528PDBVR and MCP1700-2802E/TO, the NCP4587DMX28TCG uniquely combines ultra-small XDFN-6 packaging, tri-mode current optimization, and integrated output discharge - making it optimal for space- and battery-constrained imaging applications requiring rapid power-state transitions.

FAQ
What is the output voltage tolerance of the NCP4587DMX28TCG over temperature?
The NCP4587DMX28TCG delivers ±1% output voltage accuracy at TJ = 25°C for VOUT > 2 V. Over the full operating range (−40°C to +85°C), output voltage remains within ±1.5% (−20 mV to +30 mV deviation for 2.8 V nominal), as specified in the Electrical Characteristics table under "Output Voltage" test conditions.
Does the NCP4587DMX28TCG require an external resistor divider for output setting?
No, the NCP4587DMX28TCG is a fixed-output LDO with factory-trimmed 2.8 V regulation. It does not use external feedback resistors - the output voltage is internally set and requires no external components beyond input/output ceramic capacitors (≥0.47 µF each).
How does the AE pin affect the operation of the NCP4587DMX28TCG?
The AE pin selects between automatic tri-mode operation (AE = low or floating) and permanent Fast Mode (AE = high). In automatic mode, the NCP4587DMX28TCG switches to low-power mode below ~1–2 mA load and fast mode above ~8 mA. When AE is high, it remains in fast mode regardless of load, optimizing transient response at the cost of higher quiescent current (55 µA).
What is the purpose of the NC pin on the NCP4587DMX28TCG XDFN-6 package?
Pin 5 of the NCP4587DMX28TCG in XDFN-6 package is designated NC (No Connection). It has no internal connection and must remain unconnected - neither tied to GND, VIN, nor any other node. Soldering or biasing this pin may compromise reliability or violate absolute maximum ratings.
Is the NCP4587DMX28TCG compatible with 0.47 µF ceramic output capacitors?
Yes, the NCP4587DMX28TCG is explicitly characterized and guaranteed stable with 0.47 µF X5R or X7R ceramic capacitors (COUT). Unlike many older LDOs, it imposes no minimum ESR requirement - enabling use of small, low-profile, high-performance MLCCs without risk of oscillation.
