Product details
Overview
NCP4587DMX33TCG from onsemi is a 150 mA tri-mode CMOS LDO voltage regulator with 3.3 V fixed output, ultra-low dropout (120 mV typ. at 150 mA), ±1% output accuracy (VOUT > 2 V), and auto-switching between low-power and fast-response modes based on load current. It features an Auto Eco (AE) pin for permanent fast mode selection and integrated output discharge in the D-series variant, targeting power-sensitive portable imaging and communication systems.
For engineers reviewing the NCP4587DMX33TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.4–5.25 V input range, 1.0 µA quiescent current in low-power mode, 55 µA supply current in fast mode, 70 dB PSRR at 1 kHz, and compatibility with ceramic output capacitors down to 1 µF.
Technical Context
The NCP4587DMX33TCG implements a CMOS-based LDO architecture with dual operational modes: low-power mode (1.0 µA IQ) below ~1–2 mA load and fast-response mode (55 µA IGND) above ~8 mA, triggered automatically or forced via the AE pin. Its internal N-channel pass transistor enables very low dropout-120 mV typical at 150 mA for VOUT ≥ 2.6 V-and supports stable regulation with 1 µF ceramic output capacitance.
It integrates current fold-back protection, a dedicated output discharge transistor (D-series feature), and precise enable/CE logic with 1.0 V high-threshold and 0.4 V low-threshold. The device operates across −40°C to +85°C ambient and is qualified per AEC-Q100 stress test standards for automotive-adjacent reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±1% (at TJ = 25°C, VOUT > 2 V), enabling direct powering of 3.3 V logic rails without external feedback. |
| Max Output Current | 150 mA continuous, sufficient for sensor interfaces, camera modules, and low-power microcontrollers. |
| Dropout Voltage | 120 mV typical at 150 mA (VIN ≥ VOUT + 0.12 V), allowing operation from single-cell Li-ion or 3.6 V supply with margin. |
| Quiescent Current | 1.0 µA in low-power mode (IOUT < 2 mA), minimizing battery drain in standby states of portable devices. |
| PSRR | 70 dB at 1 kHz in fast mode, suppressing ripple from noisy DC-DC converters feeding the LDO input. |
| Operating Input Range | 1.4 V to 5.25 V, supporting wide-input applications including multi-cell battery packs and USB-powered systems. |
| Thermal Resistance | RJA = 250 °C/W (XDFN package), requiring minimal PCB copper area for thermal management at full load. |
Pinout & Package
The NCP4587DMX33TCG is housed in a Pb-free XDFN-6 package (1.2 mm × 1.2 mm × 0.4 mm), optimized for space-constrained portable designs. Its compact footprint and low profile support high-density PCB layouts in cameras and wearables.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input voltage supply | Accepts 1.4–5.25 V; requires local 1 µF ceramic decoupling capacitor for stability and transient response. |
| GND | Ground reference | Common return path for input/output currents; must be low-impedance and connected directly to power plane. |
| CE | Chip enable (active-high) | Pulls up internally; tie to VIN if always-on operation required; enables system-level power sequencing control. |
| VOUT | Regulated output | Delivers stable 3.3 V; supports 1 µF ceramic output capacitor; includes integrated discharge path in D-series. |
| AE | Auto Eco mode select | Drives high to force permanent fast mode (55 µA IQ); left floating or low for automatic tri-mode switching. |
| NC | No connection | Pin 5 is unconnected and must not be soldered or biased; no electrical function or thermal role. |
Key Features
| Feature | Design Value |
|---|---|
| Tri-mode operation | Automatically switches between low-power (1.0 µA), fast (55 µA), and standby (0.1 µA) modes based on real-time load demand. |
| Integrated output discharge | D-series-specific NMOS switch discharges VOUT rapidly during shutdown, preventing residual voltage hold-up in powered-down subsystems. |
| Ceramic capacitor stability | Stable with ≥1 µF X5R/X7R ceramic output capacitors-no ESR requirements-reducing BOM count and board area. |
| High PSRR in fast mode | 70 dB rejection at 1 kHz enables clean 3.3 V rail even when fed from noisy switcher outputs or shared power domains. |
| Ultra-thin XDFN package | 0.4 mm height and 1.2 mm × 1.2 mm footprint meet strict Z-height constraints in slim mobile and imaging modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3302E/MB | Fixed 3.3 V, 250 mA, 1.6 µA IQ, no AE pin or auto mode switching; SC-70-5 package. | Lacks tri-mode intelligence and output discharge; suited for static low-IQ needs but less responsive to dynamic loads. | Select when absolute minimum quiescent current dominates over transient performance and discharge control. |
| Torex XC6219B332MR-G | Fixed 3.3 V, 150 mA, 1.0 µA IQ, CE-only control, SOT-25 package; no AE pin or fast-mode boost. | Single-mode operation only; lower PSRR (65 dB @ 1 kHz); lacks integrated discharge transistor. | Choose for cost-sensitive, space-tolerant designs where fast transient recovery and output discharge are non-critical. |
Compared with MCP1700T-3302E/MB and XC6219B332MR-G, the NCP4587DMX33TCG uniquely delivers adaptive power efficiency via tri-mode operation, guaranteed 70 dB PSRR, and D-series output discharge-making it optimal for battery-powered imaging and wireless systems demanding both ultra-low standby current and high dynamic performance.

FAQ
What is the output voltage tolerance of the NCP4587DMX33TCG over temperature?
The NCP4587DMX33TCG maintains ±1.5% output voltage accuracy across −40°C to +85°C ambient temperature for VOUT > 2 V, verified per datasheet Electrical Characteristics table. At 25°C, tolerance tightens to ±1.0%, and output voltage drift is limited to ±50 ppm/°C, ensuring stable 3.3 V regulation in thermally varying portable environments.
Does the NCP4587DMX33TCG require an external resistor divider for output setting?
No, the NCP4587DMX33TCG is a fixed-output LDO with factory-trimmed 3.3 V regulation. It does not use external feedback resistors-its output voltage is set internally and specified as ±1% accurate at 25°C. This eliminates layout complexity, resistor tolerance errors, and board space associated with adjustable LDOs.
How does the AE pin affect the NCP4587DMX33TCG's quiescent current and transient response?
When the AE pin is driven high (>1.0 V), the NCP4587DMX33TCG locks into permanent fast mode with 55 µA supply current and optimized transient response. When AE is low (<0.4 V) or floating, it operates in auto-switching tri-mode-dropping to 1.0 µA IQ under light loads (<2 mA) and boosting to fast mode above ~8 mA, balancing efficiency and performance dynamically.
Is the NCP4587DMX33TCG compatible with 1 µF ceramic output capacitors?
Yes, the NCP4587DMX33TCG is explicitly characterized and guaranteed stable with 1 µF X5R or X7R ceramic output capacitors-no minimum ESR requirement. This simplifies design, reduces component count, and avoids the size and aging issues of tantalum alternatives, as confirmed in the Application Information section of the datasheet.
What protection features are integrated into the NCP4587DMX33TCG?
The NCP4587DMX33TCG includes current fold-back protection (limiting short-circuit current to ~50 mA), thermal shutdown (triggering at TJ ≈ 150°C), and reverse-current blocking. As a D-series part, it also integrates an active output discharge transistor activated during CE-driven shutdown-preventing VOUT from floating or holding charge after disable.
