Product details
Overview
NCP583XV29T2G from onsemi is a 2.9 V fixed-output, ultra-low quiescent current (1.0 µA typical) CMOS low-dropout linear regulator in SOT-563 package, featuring enable control, 250 mV dropout at 150 mA, ±2% output voltage accuracy, and operation from 1.7 V to 6.0 V input - designed for battery-powered portable instrumentation requiring stable low-power bias.
For engineers reviewing the NCP583XV29T2G datasheet, pinout, applications, or equivalent options, key selection criteria include shutdown current (0.1 µA), thermal resistance (200 °C/W), load regulation (20 mV), and compatibility with 0.1 µF ceramic output capacitance in space-constrained handheld devices.
Technical Context
The NCP583XV29T2G implements a CMOS-based LDO architecture with internal bandgap reference, error amplifier, and foldback current limiting. Its CE pin enables active-high logic control with 1.2 V high-threshold and 0.3 V low-threshold, supporting deep-sleep mode entry in portable systems.
It delivers regulated 2.9 V output across −40°C to +85°C ambient, with ±100 ppm/°C temperature coefficient and ripple rejection up to 60 dB at 1 kHz (with 1 µF output cap). Input transient response shows <50 µs recovery under 30 mA load step with 1 µF output capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.9 V ±2% - ensures precise bias for 3.0 V–3.3 V logic rails without external feedback. |
| Quiescent Current | 1.0 µA typical - extends battery life in always-on sensor nodes and standby modes. |
| Dropout Voltage | 250 mV at 150 mA - supports operation down to Vin = 3.15 V while maintaining regulation. |
| Line Regulation | 0.05%/V - minimizes output drift during battery discharge from 4.2 V to 3.0 V. |
| Load Regulation | 20 mV (1 µA–150 mA) - maintains stable voltage across dynamic current profiles in portable gear. |
| Shutdown Current | 0.1 µA - enables true zero-power disable for energy harvesting or long-term storage. |
| Thermal Resistance | 200 °C/W (SOT-563) - allows 150 mA continuous output at TA ≤ 75°C without derating. |
Pinout & Package
SOT−563 (Case 463A), 6-pin surface-mount package with 1.6 mm × 1.2 mm footprint, 0.65 mm pitch, and exposed pad not connected internally. Pin 4 is NC; Pins 2 and 5 are both GND for enhanced thermal and ground integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vin | Input supply rail (1.7–6.0 V); requires 1.0 µF ceramic decoupling to GND per datasheet. |
| 2 | GND | Primary power ground; connects to PCB ground plane for noise immunity and thermal conduction. |
| 3 | Vout | Regulated 2.9 V output; requires 0.1 µF ceramic capacitor placed adjacent to pin for stability. |
| 4 | NC | No internal connection; must be left floating or tied to GND per layout best practice. |
| 5 | GND | Secondary ground terminal; electrically identical to Pin 2, improves grounding in high-noise environments. |
| 6 | CE | Active-high enable input; drives high (>1.2 V) to activate regulator, low (<0.3 V) to enter shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 1.0 µA typical enables >1-year battery life in coin-cell–powered IoT sensors. |

FAQ
What is the maximum input voltage rating for the NCP583XV29T2G?
The NCP583XV29T2G has a maximum input voltage rating of 6.5 V, as specified in the Absolute Maximum Ratings table. However, the recommended operating input voltage range is 1.7 V to 6.0 V per Electrical Characteristics. Exceeding 6.5 V risks permanent damage, and operation above 6.0 V may degrade regulation accuracy or thermal performance. Always observe the 6.5 V absolute limit in system-level design.
Does the NCP583XV29T2G require an external output capacitor, and what value is recommended?
Yes, the NCP583XV29T2G requires an external ceramic output capacitor for stability. The datasheet specifies a minimum of 0.1 µF and recommends 1.0 µF for optimal transient response and ripple rejection. A low-ESR X5R or X7R ceramic capacitor placed physically close to the Vout and GND pins is mandatory - omitting or undersizing this capacitor can cause oscillation or poor load regulation in the NCP583XV29T2G.
What is the function of Pin 4 (NC) on the NCP583XV29T2G SOT-563 package?
Pin 4 of the NCP583XV29T2G is designated NC (No Connect) - it has no internal electrical connection and must remain unconnected in the circuit. While some layouts tie NC pins to GND for mechanical stability, the datasheet does not recommend or require this for the NCP583XV29T2G. Leaving Pin 4 floating avoids unintended coupling paths and aligns with onsemi's validated layout guidance for the SOT-563 variant.
How does the enable (CE) pin behavior affect power sequencing in systems using the NCP583XV29T2G?
The CE pin on the NCP583XV29T2G is active-high with a 1.2 V typical threshold. When CE is pulled below 0.3 V, the device enters shutdown with only 0.1 µA current draw. This allows precise power sequencing: host MCU GPIO can assert CE after main rail stabilization, and deassert it before system sleep to cut bias current. No external pull-up is required if driven actively, but a weak pull-down ensures default-off behavior during reset.
Can the NCP583XV29T2G be used with input voltages below its nominal output voltage?
No - the NCP583XV29T2G is a low-dropout linear regulator and cannot operate with input voltage below the sum of its output voltage and dropout voltage. At 150 mA load, dropout is 250 mV, so Vin must be ≥3.15 V to maintain 2.9 V regulation. Below that, output collapses linearly. It is not a buck-boost or charge-pump device; operation below dropout results in pass-through behavior with no regulation, risking downstream circuit malfunction.
