Product details
Overview
NCP585HSN10T1G from onsemi is a tri-mode 300 mA CMOS low-dropout regulator with enable, designed for portable battery-powered systems requiring precise 1.0 V output, ultra-low quiescent current (80 µA in Fast Transient mode), and high PSRR (70 dB at 1 kHz). It operates across −40°C to +85°C and supports input voltages up to 6.5 V.
For engineers reviewing the NCP585HSN10T1G datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin functions, real-world use cases in handheld instrumentation and camcorders, and two confirmed alternative parts with documented functional differences.
Technical Context
The NCP585HSN10T1G implements three operational modes-Chip Enable (CE), Fast Transient (FT), and Low Power (LP)-selected via the ECO pin: FT mode (ECO = Vin) prioritizes transient response and load regulation (15 mV), while LP mode (ECO = GND) minimizes quiescent current to 3.5 µA for battery longevity.
Its internal architecture includes fold-back current limiting, auto-discharge capability (in active-high variants), and a precision bandgap reference enabling ±2% output voltage accuracy over temperature and line/load variations. The device requires no external compensation and supports stable operation with 1.0 µF ceramic output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0 V ±2% (typical accuracy ensures stable core supply for 1.0 V logic rails) |
| Max Output Current | 300 mA (supports moderate-power microcontrollers and sensors without thermal derating at TA ≤ 85°C) |
| Dropout Voltage | 480 mV at 300 mA (enables regulation down to Vin = 1.48 V, extending battery runtime in single-cell Li-ion or NiMH systems) |
| Quiescent Current | 80 µA in FT mode, 3.5 µA in LP mode (dual-mode optimization balances responsiveness vs. standby power) |
| PSRR | 70 dB at 1 kHz (effectively suppresses switching noise from DC-DC converters feeding the LDO input) |
| Line Regulation | 0.01%/V in FT mode (maintains tight output stability despite input voltage sag during battery discharge) |
| Operating Temp | −40°C to +85°C ambient (qualified for industrial-grade portable equipment deployment) |
Pinout & Package
Package: SOT-23-5 (Case 1212), surface-mount, Pb-free, 2.8 mm × 2.5 mm footprint with exposed pad not present in this variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Vin | Power input | Accepts 1.4–6.5 V DC; requires 1.0 µF ceramic decoupling to GND per layout guidelines |
| 2 - GND | Ground reference | Primary return path for load current and internal bias; must connect to low-impedance PCB ground plane |
| 3 - CE | Enable control | Active-high enable: drives output when CE ≥ 1.0 V; pulls output to GND when CE ≤ 0.3 V |
| 4 - ECO | Mode selection | FT mode when tied to Vin; LP mode when tied to GND; determines Iq, load regulation, and PSRR behavior |
| 5 - Vout | Regulated output | Delivers stable 1.0 V ±2%; requires 1.0 µF low-ESR ceramic capacitor placed adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Tri-mode operation | Hardware-selectable CE/FT/LP modes via ECO pin-no firmware overhead required for power-state transitions |
| Ultra-low dropout | 480 mV at 300 mA enables >90% efficiency at 1.0 V output from 1.5 V input sources (e.g., alkaline/NiMH) |
| High PSRR | 70 dB at 1 kHz reduces ripple from upstream switchers, eliminating need for additional LC filtering in space-constrained designs |
| Low temp drift | 100 ppm/°C output voltage coefficient ensures <±1% total variation across −40°C to +85°C operating range |
| Fold-back protection | Current limit reduces output current under short-circuit conditions, preventing thermal runaway and enabling safe auto-recovery |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1002E/TT | Fixed 1.0 V, 250 mA max, 6 µA IQ, no tri-mode or ECO pin | Lacks dynamic mode switching; suited only for static ultra-low-power use | Select when design requires minimal IQ without transient performance trade-offs |
| Torex XC6206P102MR-G | Fixed 1.0 V, 250 mA max, 1 µA IQ, no enable or mode pin | No CE or ECO functionality; limited to always-on or external FET-controlled shutdown | Choose for cost-sensitive, non-enable applications where 1 µA standby suffices |
Compared with MCP1700T-1002E/TT and XC6206P102MR-G, the NCP585HSN10T1G uniquely delivers hardware-selectable fast-transient and low-power modes in a single SOT-23-5 package-enabling both responsive operation and sub-4 µA standby without external circuitry or firmware intervention.

FAQ
What is the maximum input voltage rating for the NCP585HSN10T1G?
The NCP585HSN10T1G has an absolute maximum input voltage (Vin) rating of 6.5 V. Operation above this level risks permanent damage. For reliable long-term use, the recommended maximum operating input voltage is 6.0 V, as specified in the Electrical Characteristics table under Recommended Operating Conditions.
Does the NCP585HSN10T1G support active discharge of the output capacitor?
No, the NCP585HSN10T1G does not include active output discharge. Only the "DSAN" and "DSN" variants (e.g., NCP585DSN10T1G) feature auto-discharge functionality. The "HSN" suffix denotes active-high enable without discharge, confirmed by the Ordering Information table and absence of discharge-related specs in the Electrical Characteristics section.
What output capacitor value and type are recommended for stable operation of the NCP585HSN10T1G?
A 1.0 µF ceramic capacitor with low ESR is recommended for the NCP585HSN10T1G output. The datasheet explicitly states this value in the Application Information section and confirms stability across load currents up to 300 mA in both FT and LP modes, with no unstable region observed for 1.0 µF in LP mode per Figure 33.
How does the ECO pin affect load regulation performance in the NCP585HSN10T1G?
When the ECO pin is tied to Vin (FT mode), the NCP585HSN10T1G achieves 15 mV load regulation across 1–300 mA. When ECO is tied to GND (LP mode), load regulation degrades to 40 mV across 1–100 mA. This trade-off reflects the internal bias current reduction that enables 3.5 µA quiescent current in LP mode.
Is the NCP585HSN10T1G pin-compatible with other devices in the NCP585 family?
Yes, all SOT-23-5 variants in the NCP585 family-including NCP585HSN10T1G, NCP585HSN09T1G, and NCP585LSN12T1G-share identical pinout (Vin, GND, CE, ECO, Vout) and footprint. Voltage and enable polarity differences do not affect mechanical or electrical pin mapping, enabling drop-in replacement within the same package variant.
