Product details
Overview
NCP584HSN15T1G from onsemi is a tri-mode 200 mA CMOS low-dropout (LDO) regulator with enable and ECO pin for mode selection, delivering a fixed 1.5 V output. It supports Chip Enable (CE), Fast Transient (FT), and Low Power (LP) modes, features 40 µA quiescent current in LP mode, 300 mV dropout at 200 mA, and ±2% output voltage accuracy - ideal for battery-powered portable equipment requiring stable low-voltage rail generation.
For engineers reviewing the NCP584HSN15T1G datasheet, pinout, applications, or equivalent options, key selection criteria include tri-mode operation flexibility, ultra-low Iq in LP mode, dropout performance at 1.5 V output, SOT23−5 package constraints, and compatibility with ceramic output capacitors down to 40 mΩ ESR in LP mode.
Technical Context
The NCP584HSN15T1G implements a CMOS-based LDO architecture with internal reference, error amplifier, and pass transistor. Its tri-mode control is managed via the ECO pin: FT mode (ECO = VIN) prioritizes transient response and ripple rejection (75 dB @ 1 kHz), while LP mode (ECO = GND) minimizes quiescent current to 40 µA at 1.5 V output.
It integrates fold-back current limiting, thermal shutdown, and operates across −40°C to +85°C ambient. Input voltage range is 1.4 V to 6.0 V, supporting single-cell Li-ion, multi-cell alkaline, or regulated intermediate rails. The CE pin enables full shutdown with 0.1 µA leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% (±3% in LP mode); ensures stable core logic or sensor supply under load and temperature variation. |
| Max Output Current | 200 mA continuous; sufficient for microcontrollers, RF transceivers, or small FPGA I/O banks. |
| Dropout Voltage | 300 mV at 200 mA (VOUT = 1.5 V); enables operation from 1.8 V input, extending battery runtime in low-VIN conditions. |
| Quiescent Current | 40 µA in LP mode (VOUT ≤ 1.5 V); critical for always-on subsystems in portable devices. |
| PSRR | 75 dB @ 1 kHz; suppresses switching noise from DC-DC converters feeding the LDO input. |
| Line Regulation | 0.05%/V in FT mode; maintains tight output stability despite input rail sag during high-current pulses. |
| Load Regulation | 10 mV (0–100 mA, LP mode); limits output shift during sleep-to-active transitions in MCU peripherals. |
| Temp Coefficient | 100 ppm/°C; contributes <±1.5 mV drift over −40°C to +85°C, supporting precision analog front-ends. |
Pinout & Package
SOT23−5 package (Case 1212), 2.8 mm × 2.5 mm footprint, 1.0–1.3 mm height, Pb-free, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Vin | Power input | Accepts 1.4–6.0 V; requires ≥1.0 µF input decoupling close to pin for stability. |
| 2 - GND | Ground reference | Common return for input, output, and control pins; must be low-impedance PCB plane. |
| 3 - CE | Enable control | Active-high enable; drives output when VCE ≥ 1.0 V; pulls output to shutdown state at VCE ≤ 0.3 V. |
| 4 - ECO | Mode selection | FT mode when tied to VIN; LP mode when tied to GND; no floating allowed. |
| 5 - Vout | Regulated output | Delivers 1.5 V ±2%; requires ≥2.2 µF output capacitor (tantalum or ceramic with ≥40 mΩ ESR in LP mode). |
Key Features
| Feature | Design Value |
|---|---|
| Tri-mode operation (CE/FT/LP) | Enables dynamic trade-off between efficiency (LP), transient response (FT), and full enable/disable control (CE) without external circuitry. |
| Ultra-low Iq in LP mode | 40 µA at 1.5 V output allows >1-year battery life in coin-cell–powered IoT sensors with periodic wake-up. |
| Low dropout at 1.5 V | 300 mV dropout enables use with 1.8 V sources (e.g., buck converter output), maximizing energy extraction from aging batteries. |
| High PSRR (75 dB @ 1 kHz) | Effectively isolates noise-sensitive analog circuits (e.g., ADC references) from noisy digital power domains. |
| Fold-back current protection | Limits short-circuit current to ~50 mA, preventing thermal runaway and enabling safe operation into fault conditions. |
| −40°C to +85°C operation | Validated performance across industrial temperature range, suitable for automotive cabin and outdoor portable instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1826S-1502E/DB | Fixed 1.5 V, 300 mA, 240 mV dropout @ 200 mA, 55 µA Iq (typ), no tri-mode | Single-mode operation only; lacks ECO-controlled LP/FT switching | Choose when simplified control and higher current headroom are preferred over dynamic mode optimization. |
| Torex XC6219B152MR-G | Fixed 1.5 V, 200 mA, 250 mV dropout @ 100 mA, 1 µA Iq (standby), no CE/ECO flexibility | No enable or mode pin; ultra-low Iq but no fast-transient capability | Choose for lowest possible quiescent current where transient performance is secondary and enable control is unnecessary. |
Compared with MCP1826S-1502E/DB and XC6219B152MR-G, the NCP584HSN15T1G uniquely balances ultra-low Iq, fast transient response, and programmable mode selection in a compact SOT23−5 package - making it optimal for systems requiring adaptive power management rather than static low-power or high-current operation alone.

FAQ
What is the maximum input voltage for the NCP584HSN15T1G?
The NCP584HSN15T1G supports a maximum input voltage of 6.0 V under recommended operating conditions. Absolute maximum rating is 6.5 V, but sustained operation above 6.0 V may impact reliability or parametric performance. For 1.5 V output, typical minimum input is 1.8 V to maintain regulation with margin.
How does the ECO pin affect the NCP584HSN15T1G's quiescent current and performance?
When the ECO pin is tied to GND, the NCP584HSN15T1G enters Low Power (LP) mode, reducing quiescent current to 40 µA at 1.5 V output. When tied to VIN, it enters Fast Transient (FT) mode, increasing Iq to 40 µA but improving PSRR and load transient response. The ECO pin must not be left floating.
Can the NCP584HSN15T1G be used with ceramic output capacitors?
Yes - the NCP584HSN15T1G supports ceramic output capacitors. In LP mode, minimum ESR is 40 mΩ across all loads. In FT mode, minimum ESR depends on output current and voltage (e.g., ~100 mΩ at 200 mA for 1.5 V output). A series resistor (~1 Ω) may be added for stability if using low-ESR ceramics.
What is the dropout voltage of the NCP584HSN15T1G at 200 mA load?
The dropout voltage of the NCP584HSN15T1G is 300 mV at 200 mA load and 25°C ambient, specified for VOUT = 1.5 V. This value increases slightly at lower temperatures and decreases at higher temperatures, with typical curves showing 250–350 mV across −40°C to +85°C.
Does the NCP584HSN15T1G include thermal shutdown and current limiting?
Yes - the NCP584HSN15T1G integrates both thermal shutdown and fold-back current limiting. Output short-circuit current is limited to approximately 50 mA, and thermal protection activates at junction temperatures exceeding 125°C, disabling the output until safe temperature is restored.
