Product details
Overview
NCP585HSAN09T1G from onsemi is a tri-mode 300 mA CMOS low-dropout regulator with enable and ECO pin control, delivering fixed 0.9 V output in HSON-6 package. It supports Chip Enable (CE), Fast Transient (FT), and Low Power (LP) modes, achieves 550 mV dropout at 300 mA, maintains ±2% output accuracy in FT mode, and draws only 3.5 µA quiescent current in LP mode - ideal for battery-powered portable instrumentation requiring stable low-voltage rail generation.
For engineers reviewing the NCP585HSAN09T1G datasheet, pinout, applications, or equivalent options, key selection criteria include tri-mode operational flexibility, ultra-low Iq in LP mode, 0.9 V fixed output compatibility with sub-1 V logic domains, and HSON-6 thermal performance for space-constrained handheld designs.
Technical Context
The NCP585HSAN09T1G implements a CMOS-based LDO architecture with separate CE and ECO pins enabling dynamic mode switching between Fast Transient (ECO = Vin) and Low Power (ECO = GND) operation. Its internal reference and error amplifier maintain tight regulation across input voltages from 1.4 V to 6.0 V and load currents up to 300 mA.
Mode selection directly governs critical performance trade-offs: FT mode delivers 15 mV load regulation and 0.01%/V line regulation, while LP mode reduces Iq to 3.5 µA but relaxes accuracy to ±3% and load regulation to 40 mV - allowing system-level power/performance optimization via external ECO voltage control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.9 V - matches core voltage requirements of ultra-low-power microcontrollers and sensors. |
| Max Output Current | 300 mA - sufficient for powering SoC subsystems or multi-rail PMIC front-end stages. |
| Dropout Voltage | 550 mV at 300 mA (FT mode) - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (2.4 V min) sources. |
| Quiescent Current | 3.5 µA (LP mode, Vout < 1.6 V) - extends battery life in always-on monitoring applications. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Accuracy | ±2% (FT mode), ±3% (LP mode) - ensures reliable logic-level compliance across temperature and load. |
| Operating Input Range | 1.4 V to 6.0 V - supports wide-input battery chemistries and intermediate supply rails. |
Pinout & Package
HSON-6 package (Case 506AE), 2.9 mm × 3.0 mm × 0.7–0.9 mm profile with exposed thermal pad; optimized for high thermal conductivity on PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: Vin | Power input | Accepts 1.4–6.0 V supply; requires 1.0 µF ceramic decoupling to GND per datasheet layout guidance. |
| 2: GND | Ground reference | Primary return path for load current and internal bias; connects to exposed thermal pad for thermal dissipation. |
| 3: CE | Chip enable (active-high) | Drives regulator into shutdown (ISD = 0.1 µA) when pulled low; compatible with standard GPIO logic levels. |
| 4: Vout | Regulated output | Delivers stable 0.9 V ±2% to load; requires 1.0 µF low-ESR capacitor placed adjacent to pin per stability guidelines. |
| 5: NC | No connect | Internally unconnected; must remain floating - no external tie or routing permitted. |
| 6: ECO | Mode selection | Set to Vin for FT mode (fast response), GND for LP mode (ultra-low Iq); controls internal bias network configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Tri-mode operation | Single device supports CE-controlled shutdown, ECO-switched FT mode (high PSRR, fast transient response), and LP mode (3.5 µA Iq) - eliminates need for multiple regulators in power-managed systems. |
| Fold-back protection | Internal current limiting reduces output current during short-circuit events to limit power dissipation and prevent thermal runaway. |
| Auto-discharge disable | This variant (HSAN) lacks auto-discharge circuitry - Vout remains active after CE deassertion, preserving state in memory-backed subsystems. |
| Low temperature drift | 100 ppm/°C output voltage drift - maintains voltage integrity over −40°C to +85°C industrial ambient range without external compensation. |
| Pb-free HSON-6 | RoHS-compliant 6-pin thermally enhanced package with wettable flanks for automated optical inspection (AOI) and reliable reflow soldering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1804T-0902E/MB | Fixed 0.9 V, 150 mA max, SOT-23-5, 220 mV dropout at 150 mA, 3 µA Iq (no tri-mode) | Limited current and no ECO-controlled mode switching; suitable only for lower-power peripherals. | Select when system requires minimal Iq and <150 mA load, but does not need dynamic mode adaptation. |
| TLC7701QDCKR | Adjustable output (1.2–5.5 V), 150 mA, SC70-5, 300 mV dropout at 150 mA, 1.2 µA Iq, no ECO pin | Requires external resistor divider; lacks tri-mode capability and 0.9 V fixed option. | Choose for designs needing programmable voltage or tighter Iq, accepting reduced current capability and loss of mode agility. |
Compared with MCP1804T-0902E/MB and TLC7701QDCKR, the NCP585HSAN09T1G uniquely delivers 300 mA output, tri-mode flexibility via ECO pin, and guaranteed 0.9 V fixed output - making it the only option among the three capable of supporting high-current, dynamically power-gated subsystems in compact HSON-6 form factor.

FAQ
What is the maximum input voltage rating for the NCP585HSAN09T1G?
The NCP585HSAN09T1G has an absolute maximum input voltage rating of 6.5 V on the Vin pin. The recommended operating input voltage range is 1.4 V to 6.0 V, as specified in the Electrical Characteristics table. Exceeding 6.5 V may cause permanent damage to the device.
Does the NCP585HSAN09T1G include auto-discharge functionality?
No, the NCP585HSAN09T1G does not include auto-discharge. Per the Ordering Information table, "HSAN" denotes Active High operation *without* auto-discharge, unlike "DSAN" variants. When CE is deasserted, Vout remains active until Vin drops below regulation threshold - preserving state in memory-backed circuits.
How does the ECO pin affect output voltage accuracy in the NCP585HSAN09T1G?
The ECO pin selects operating mode: when pulled to Vin, the NCP585HSAN09T1G operates in Fast Transient (FT) mode with ±2% output voltage accuracy; when pulled to GND, it enters Low Power (LP) mode with relaxed ±3% accuracy. This trade-off enables firmware-directed optimization between precision and quiescent current.
What is the thermal performance of the NCP585HSAN09T1G in its HSON-6 package?
The NCP585HSAN09T1G in HSON-6 (Case 506AE) has a maximum power dissipation rating of 400 mW. Its exposed thermal pad must be soldered to a PCB copper pour for effective heat transfer; thermal resistance θJA is not explicitly stated in the datasheet but typical HSON-6 devices achieve ~120°C/W with 1-in² 2-oz copper.
Can the NCP585HSAN09T1G be used with ceramic output capacitors?
Yes, the NCP585HSAN09T1G is stable with 1.0 µF ceramic output capacitors, as confirmed in the Application Information section. The datasheet recommends low-ESR ceramics and specifies stable operation down to 0.1 µF in FT mode - enabling compact, high-frequency-decoupled designs without tantalum or aluminum electrolytic components.
