Product details
Overview
NCP584HSN09T1 from onsemi is a 3-mode, 200 mA low-dropout linear regulator with 0.9 V fixed output voltage, 300 mV dropout at 200 mA, ±2% output accuracy (±3% in LP mode), and ultra-low 3.5 µA quiescent current in Low Power mode - designed for battery-powered portable equipment requiring precise voltage regulation under dynamic load and supply conditions.
For engineers reviewing the NCP584HSN09T1 datasheet, pinout, applications, or equivalent options, key selection criteria include its triple-mode operation (CE/FT/LP), ECO-pin-controlled mode switching, SOT23-5 package constraints, and trade-offs between transient response speed and quiescent current across operating modes.
Technical Context
The NCP584HSN09T1 implements a CMOS-based LDO architecture with internal reference, error amplifier, and pass transistor. Its three operational modes-Chip Enable (CE), Fast Transient (FT), and Low Power (LP)-are selected via the ECO pin: FT mode (ECO = Vin) prioritizes load/transient response with 40 µA supply current, while LP mode (ECO = GND) minimizes quiescent consumption to 3.5 µA for 0.9 V output.
It supports input voltages from 1.4 V to 6.0 V, delivers up to 200 mA output current, and maintains ±2% output voltage accuracy over temperature (−40°C to +85°C) and line/load variations. Dropout voltage is specified at 300 mV (200 mA, Vout = 0.9 V), and PSRR exceeds 60 dB at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.9 V - enables direct powering of ultra-low-voltage logic cores and RF bias rails without external feedback. |
| Max Output Current | 200 mA - sufficient for microcontroller cores, sensors, and low-power wireless transceivers in portable systems. |
| Dropout Voltage | 300 mV at 200 mA - allows regulation from 1.2 V input, critical for single-cell Li-ion or NiMH battery applications. |
| Quiescent Current | 3.5 µA in LP mode - extends battery life in standby/sleep states of handheld instrumentation and wearables. |
| Output Accuracy | ±2% (±3% in LP mode) - ensures stable voltage margin for sub-1 V digital circuits with tight VDD tolerance. |
| PSRR | >60 dB at 1 kHz - suppresses switching noise from DC-DC converters feeding the LDO input rail. |
| Operating Temp | −40°C to +85°C - qualified for industrial and consumer portable environments without derating. |
Pinout & Package
SOT23-5 package (Case 1212-01), 2.8 mm × 2.5 mm footprint, 0.95 mm pin pitch, surface-mount, lead-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Vin | Input power supply | Accepts 1.4–6.0 V input; requires local 1.0 µF ceramic decoupling capacitor for stability. |
| 2 - GND | Power ground reference | Must be connected to low-impedance system ground plane to minimize noise coupling into regulation loop. |
| 3 - CE | Chip enable control | Active-high enable; pulls output to high-impedance when low, reducing system standby current. |
| 4 - ECO | Mode selection control | Drives FT mode when tied to Vin, LP mode when grounded - determines quiescent current vs. transient performance trade-off. |
| 5 - Vout | Regulated output | Delivers stable 0.9 V; requires 1.0–4.7 µF ceramic output capacitor for transient response and phase margin. |
Key Features
| Feature | Design Value |
|---|---|
| Triple-mode operation | CE, FT, and LP modes selectable via ECO pin - enables dynamic optimization of power vs. performance in firmware-controlled systems. |
| Ultra-low LP-mode IQ | 3.5 µA at Vout ≤ 1.5 V - reduces battery drain during extended sleep cycles without sacrificing wake-up latency. |
| Fast transient response | Sub-10 µs recovery from 50 mA load step (Cout = 2.2 µF) - maintains voltage integrity for burst-mode processors and radios. |
| High PSRR | 60–90 dB from 10 Hz to 100 kHz - isolates sensitive analog/RF circuitry from noisy digital supply domains. |
| Thermal shutdown | Integrated protection activates at TJ ≥ +150°C - prevents damage during sustained overload or poor PCB thermal design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-0902E/TT | Fixed 0.9 V, 250 mA, 6 µA IQ (no multi-mode), SOT23-3 package | Lacks ECO-controlled FT/LP modes; simpler enable-only control | Choose for cost-sensitive designs where dynamic mode switching is unnecessary. |

FAQ
What output voltage does the NCP584HSN09T1 provide?
The NCP584HSN09T1 provides a fixed 0.9 V output voltage. This value is factory-trimmed and guaranteed within ±2% tolerance over temperature and load conditions in normal operation, and ±3% in Low Power (LP) mode. It does not support adjustable output configurations - the "09" in the part number explicitly denotes the 0.9 V variant.
How does the ECO pin affect NCP584HSN09T1 operation?
The ECO pin selects between Fast Transient (FT) mode and Low Power (LP) mode on the NCP584HSN09T1. When ECO is tied to Vin, the device operates in FT mode with 40 µA supply current and optimized transient response. When ECO is grounded, it enters LP mode with 3.5 µA supply current - enabling extended battery life at the expense of slower load-step recovery.
What is the minimum input voltage required for NCP584HSN09T1 to regulate 0.9 V?
The NCP584HSN09T1 requires a minimum input voltage of 1.4 V to maintain regulation at 0.9 V output. This is derived from its maximum dropout specification: at 200 mA load, dropout is 300 mV, so Vin must be ≥ Vout + VDO = 0.9 V + 0.3 V = 1.2 V - but the absolute minimum rated Vin per datasheet is 1.4 V to ensure stable operation across process, voltage, and temperature corners.
Can NCP584HSN09T1 be used with ceramic output capacitors?
Yes, the NCP584HSN09T1 is fully compatible with ceramic output capacitors ranging from 1.0 µF to 4.7 µF, as confirmed in the datasheet's transient response characterization (Figures 29–30). A 2.2 µF X5R/X7R ceramic capacitor is recommended for optimal balance of stability, transient performance, and board area - no series resistance (ESR) requirements apply.
Does NCP584HSN09T1 include thermal protection?
Yes, the NCP584HSN09T1 integrates thermal shutdown protection that activates when junction temperature exceeds approximately +150°C. Once triggered, the device disables the output until temperature falls below the hysteresis threshold (~140°C), preventing permanent damage during sustained overload or inadequate PCB heat sinking.
