Product details
Overview
NCP4589DMX12TCG from onsemi is a 300 mA tri-mode CMOS LDO voltage regulator with 1.2 V fixed output, operating from 1.4 V to 5.25 V input, featuring auto-eco/fast/standby modes, 230 mV typical dropout at 300 mA, and ±1% output accuracy - deployed in portable image sensors and battery-powered camera modules.
For engineers reviewing the NCP4589DMX12TCG datasheet, pinout, applications, or equivalent options, key selection criteria include tri-mode quiescent current (1.0 µA low-power, 55 µA fast, 0.1 µA standby), AE pin-controlled mode switching, ceramic-capacitor stability, and XDFN6 1.2×1.2 mm ultra-thin packaging for space-constrained imaging subsystems.
Technical Context
The NCP4589DMX12TCG implements an adaptive tri-mode architecture: it autonomously transitions between low-power mode (<3 mA load) and fast-response mode (>8 mA load), with AE pin enabling permanent fast mode. Its internal N-channel pass transistor delivers 230 mV dropout at full 300 mA load and 2.8 V output.
It integrates current-foldback protection, 70 dB PSRR at 1 kHz in fast mode, and stable operation with ≥1 µF ceramic output capacitors. The device supports 0.02%/V line regulation and ±50 ppm/°C output voltage temperature coefficient across −40°C to +85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±1% (at VOUT > 2 V; ±20 mV for ≤2 V), enabling precise core biasing for image sensor analog front-ends. |
| Max Output Current | 300 mA continuous, supporting high-current pixel array drivers without thermal derating in XDFN6 package. |
| Dropout Voltage | 230 mV typical at 300 mA and 2.8 V output, allowing operation from single-cell Li-ion (3.0 V min) down to 1.43 V input. |
| Quiescent Current | 1.0 µA in low-power mode (VOUT ≤ 1.85 V), extending battery life in always-on camera standby states. |
| PSRR | 70 dB at 1 kHz in fast mode, suppressing switching noise from PMICs or DC-DC converters feeding the LDO input. |
| Operating Input Range | 1.4 V to 5.25 V, compatible with wide-input battery stacks, USB-powered peripherals, and multi-rail embedded systems. |
| Thermal Resistance | RJA = 250 °C/W (XDFN), enabling 400 mW power dissipation with <40°C junction rise at 25°C ambient. |
Pinout & Package
XDFN6 package: 1.2 mm × 1.2 mm × 0.4 mm ultra-thin, leadless, wettable flank design optimized for automated optical inspection and high-density PCB layouts in mobile imaging modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 1.4–5.25 V; requires local 1 µF ceramic decoupling to minimize line transients. |
| GND | Ground reference | Common return path for input/output currents; must be low-impedance and thermally coupled to PCB copper pour. |
| CE | Chip enable control | Active-high logic input (VCEH = 1.0 V); internal pull-down enables default ON operation when left unconnected. |
| VOUT | Regulated output | Delivers stable 1.2 V ±1%; requires 1 µF ceramic capacitor placed adjacent to pin for stability and transient response. |
| AE | Auto Eco mode select | Logic input (VAEH = 1.0 V) forcing permanent fast mode when high; enables automatic tri-mode switching when low. |
| NC | No connection | Unbonded pad; must remain floating - no routing or solder mask opening required. |
Key Features
| Feature | Design Value |
|---|---|
| Tri-mode dynamic current optimization | Switches automatically between 1.0 µA (low-power), 55 µA (fast), and 0.1 µA (standby) supply currents based on load, reducing average system power by >90% during idle imaging cycles. |
| Ceramic capacitor compatibility | Stable with ≥1 µF X5R/X7R ceramics only - eliminates need for costly tantalum or polymer capacitors and avoids ESR-related oscillation risks. |
| Fast transient recovery | Sub-10 µs load-step response (e.g., 1→50 mA) in fast mode, maintaining <±20 mV output deviation for burst-mode image capture timing. |
| Integrated output discharge (D version) | Internal VOUT-to-GND switch activates during disable, discharging output capacitance in <1 ms - prevents residual voltage from interfering with sequenced power-down of sensor interfaces. |
| Pb-free XDFN6 packaging | 1.2×1.2 mm footprint with wettable flanks supports fine-pitch reflow, AOI verification, and thermal performance matching SOT-23-5 while occupying 40% less board area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1804T-1202E/MB | Fixed 1.2 V, 150 mA max, 220 mV dropout, 3.5 µA IQ, SOT-23 package | Limited to lower current; lacks tri-mode and AE pin control; no auto-discharge | Select when cost sensitivity outweighs current headroom and dynamic efficiency needs. |
| Torex XC6210B122MR-G | Fixed 1.2 V, 300 mA, 250 mV dropout, 1.0 µA IQ, SOT-25 package, no AE pin | Single-mode (ultra-low IQ only); no fast-mode PSRR boost or load-triggered mode switching | Choose for static low-power applications where transient response and PSRR are secondary to minimum quiescent draw. |
Compared with MCP1804T-1202E/MB and XC6210B122MR-G, the NCP4589DMX12TCG uniquely delivers full 300 mA capability with adaptive tri-mode operation, enabling both microamp-level standby and millisecond-scale transient recovery - critical for imaging workloads with intermittent high-current bursts.

FAQ
What is the output voltage tolerance of the NCP4589DMX12TCG over temperature and load?
The NCP4589DMX12TCG provides ±1% output voltage accuracy for VOUT > 2 V at TA = 25°C; over −40°C to +85°C and 1–10 mA load, accuracy degrades to ±1.5% (±20 mV for ≤2 V outputs). This ensures reliable 1.2 V biasing for image sensor analog blocks across industrial temperature ranges.
Does the NCP4589DMX12TCG require external components for stability?
Yes - the NCP4589DMX12TCG requires a minimum 1 µF X5R/X7R ceramic capacitor on both input (CIN) and output (COUT), placed adjacent to their respective pins. Tantalum or high-ESR capacitors risk instability; parallel ceramic arrays may cause oscillation per datasheet Section "APPLICATION INFORMATION".
How does the AE pin affect the operation of the NCP4589DMX12TCG?
The AE pin on the NCP4589DMX12TCG selects between automatic tri-mode switching (AE = low) and forced fast mode (AE = high). In automatic mode, it transitions from low-power (≤2 mA load) to fast mode (≥8 mA load); in forced mode, it remains in fast mode regardless of load, optimizing PSRR and transient response at the cost of higher quiescent current.
What thermal performance can be expected from the NCP4589DMX12TCG in its XDFN6 package?
The NCP4589DMX12TCG in XDFN6 has RJA = 250 °C/W. At 300 mA output into 1.2 V (360 mW dissipation), junction temperature rise is ~90°C above ambient - requiring adequate PCB copper area. Derating to 200 mA reduces rise to ~60°C, enabling reliable operation in sealed enclosures up to +65°C ambient.
Is the NCP4589DMX12TCG pin-compatible with other packages in the NCP4589 family?
No - the NCP4589DMX12TCG uses XDFN6 (6-pin), while SC-70 and SOT-23-5 variants have different pinouts and footprints. Pin mapping differs: XDFN6 assigns AE to pin 1 and NC to pin 5; SOT-23-5 places AE on pin 4 and omits NC. PCB layout must be package-specific; no mechanical or electrical interchangeability exists.
