Product details
Overview
NCP4589DMX30TCG from onsemi is a 300 mA tri-mode CMOS LDO voltage regulator with 3.0 V fixed output, operating from 1.4 V to 5.25 V input. It features automatic switching between low-power (1.0 µA quiescent current) and fast-response (55 µA) modes based on load current, plus a dedicated Auto Eco (AE) pin for forced mode selection. It delivers ±1% output accuracy at 25°C and supports ceramic output capacitors in portable imaging and battery-powered systems.
For engineers reviewing the NCP4589DMX30TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 230 mV dropout at 300 mA/2.8 V, 70 dB PSRR in fast mode, tri-mode current optimization, XDFN-6 1.2×1.2 mm package, and auto-discharge functionality for rapid output shutdown.
Technical Context
The NCP4589DMX30TCG implements a CMOS-based LDO architecture with integrated N-channel pass transistor and fold-back current limiting. Its tri-mode operation-low-power, fast, and standby-is governed by internal load-current thresholds (IOUTL = 1–2 mA, IOUTH = 8 mA) and externally controllable via the AE pin.
It integrates an output discharger transistor activated during CE disable, enabling rapid VOUT discharge. The device achieves stable regulation with ≥1 µF ceramic output capacitance and exhibits 0.02%/V line regulation in fast mode, supporting dynamic supply rejection across 10 Hz–100 kHz bandwidths.
Key Specifications

FAQ
What is the output voltage tolerance of the NCP4589DMX30TCG over temperature?
The NCP4589DMX30TCG maintains ±1% output voltage accuracy at TJ = 25°C for VOUT > 2 V. Over the full operating temperature range (−40°C to +85°C), output voltage drift is specified as ±2.5% (±0.075 V) for 3.0 V nominal output, confirmed in the Electrical Characteristics table under "Output Voltage" test conditions.
Does the NCP4589DMX30TCG require external components for stability?
No, the NCP4589DMX30TCG is internally compensated and stable with a minimum 1 µF ceramic output capacitor. The datasheet explicitly states it is "stable with ceramic capacitors" and recommends placing COUT as close as possible to VOUT and GND pins. No ESR requirements or additional compensation networks are needed.
How does the AE pin affect the operation of the NCP4589DMX30TCG?
The AE pin on the NCP4589DMX30TCG selects between automatic tri-mode switching (AE = low) and forced fast mode (AE = high). When AE is pulled low (<0.4 V), the device autonomously transitions between low-power and fast modes based on load current. When AE is high (>1.0 V), it remains in fast mode regardless of load, ensuring consistent 55 µA quiescent current and optimal transient response.
What is the purpose of the NC pin on the NCP4589DMX30TCG XDFN package?
The NC (No Connection) pin on the NCP4589DMX30TCG XDFN-6 package is not electrically bonded and serves no functional role. Per the datasheet Pin Function Description, it must remain unconnected on the PCB. Routing traces or applying solder to this pin may compromise reliability or violate manufacturing specifications.
Can the NCP4589DMX30TCG be used with a 1.8 V input supply?
Yes, the NCP4589DMX30TCG supports input voltages as low as 1.4 V, making it compatible with a 1.8 V input. However, with VIN = 1.8 V and VOUT = 3.0 V, regulation is impossible-the device requires VIN ≥ VOUT + dropout. At 300 mA load, dropout is 230 mV, so minimum VIN = 3.23 V. Below that, the part operates in dropout and cannot regulate 3.0 V.
