Product details
Overview
NCP583XV28T2G from onsemi is a 2.8 V, 150 mA ultra-low quiescent current CMOS LDO regulator in SOT-563 package, featuring 250 mV dropout at full load, ±2% output voltage accuracy, and 1.0 µA quiescent current - designed for battery-powered portable equipment requiring stable low-power voltage regulation.
For engineers reviewing the NCP583XV28T2G datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage range (1.7–6.0 V), shutdown current (0.1 µA), thermal resistance (200 °C/W), output capacitor compatibility (0.1–1.0 µF ceramic), and enable logic polarity (active-high).
Technical Context
The NCP583XV28T2G implements a CMOS-based LDO architecture with internal bandgap reference, error amplifier, and foldback current limiting. It uses an active-high enable pin (CE) to control regulator operation and supports input voltages up to 6.5 V while maintaining regulation down to Vin = Vout + 0.25 V at 150 mA.
Its low temperature drift (±100 ppm/°C) and excellent line regulation (0.05%/V) ensure stable 2.8 V output across −40°C to +85°C ambient and varying input conditions. The device requires no external compensation and is optimized for use with low-ESR ceramic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.8 V ±2% - ensures precise rail generation for 2.8 V logic or analog circuitry without post-regulation trimming. |
| Max Output Current | 150 mA - sufficient to power microcontrollers, sensors, or RF front-ends in compact portable systems. |
| Dropout Voltage | 250 mV at 150 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (3.2 V min) sources. |
| Quiescent Current | 1.0 µA typical - extends battery life in always-on or sleep-mode applications such as wearables and remote sensors. |
| Shutdown Current | 0.1 µA typical - reduces system standby leakage when CE is low, critical for multi-year battery operation. |
| Line Regulation | 0.05%/V - minimizes output variation during battery discharge or supply ripple, improving ADC reference stability. |
| Thermal Resistance | 200 °C/W (SOT-563) - defines junction-to-ambient rise under full load; requires minimal PCB copper for thermal management. |
Pinout & Package
SOT-563 package (Case 463A), 6-pin surface-mount, 1.6 mm × 1.2 mm × 0.6 mm body, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Vin) | Input Power Supply | Accepts 1.7–6.0 V DC input; requires 1.0 µF ceramic decoupling to GND per datasheet recommendation. |
| 2 (GND) | Power Ground | Primary ground return path; electrically tied to pin 5 (second GND) internally in SOT-563 package. |
| 3 (Vout) | Regulated Output | Delivers stable 2.8 V; requires 0.1 µF ceramic capacitor placed close to pin for transient response and stability. |
| 4 (NC) | No Connect | Internally unconnected; must remain floating - no routing or soldering permitted. |
| 5 (GND) | Secondary Ground | Dedicated ground terminal; improves thermal dissipation and reduces ground loop impedance in high-frequency layouts. |
| 6 (CE) | Enable Control | Active-high logic input; drives regulator ON when ≥1.2 V, OFF when ≤0.3 V; draws <100 nA in shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 1.0 µA typical - enables >10-year battery life in coin-cell-powered IoT endpoints with periodic wake-up. |
| Foldback current limit | 40 mA short-circuit current - protects IC and source during output fault while minimizing thermal stress. |
| Low temperature drift | ±100 ppm/°C - maintains output accuracy across industrial temperature range without calibration. |
| Input voltage range | 1.7–6.0 V - supports direct connection to Li-ion, Li-Po, NiMH, or dual-alkaline batteries without pre-regulation. |
| Capacitor compatibility | 0.1–1.0 µF ceramic only - eliminates need for tantalum or electrolytic capacitors, reducing BOM cost and size. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2802E/TT | 2.8 V, 250 mA, 1.6 µA IQ, SOT-23-5; higher IQ and output current, different pinout. | Requires PCB redesign due to 5-pin SOT-23 vs. 6-pin SOT-563; better for higher-current loads but less optimal for ultra-low-IQ priority. | Select if >150 mA output or tighter layout spacing is needed; verify CE logic compatibility and thermal derating. |
| TNPA2828B | 2.8 V, 150 mA, 0.9 µA IQ, SOT-563; identical package and enable polarity, but ±2.5% accuracy and no foldback protection. | Same footprint and pinout - drop-in replacement possible for non-safety-critical designs where ±2.5% tolerance is acceptable. | Choose when absolute minimum IQ is paramount and foldback protection is not required; validate ripple rejection performance. |
Compared with MCP1700T-2802E/TT and TNPA2828B, the NCP583XV28T2G offers superior line regulation (0.05%/V vs. ≥0.1%/V), integrated foldback protection, and guaranteed ±2% accuracy - making it preferred for precision analog and long-life battery systems where reliability and specification margin matter.

FAQ
What is the maximum input voltage rating for the NCP583XV28T2G?
The NCP583XV28T2G has an absolute maximum input voltage rating of 6.5 V on the Vin pin and 6.5 V on the CE pin. Its recommended operating input voltage range is 1.7 V to 6.0 V, as specified in the Electrical Characteristics table. Exceeding 6.5 V may cause permanent damage. For reliable operation with Li-ion batteries, ensure the input does not exceed 4.3 V during charging phases unless protected by external circuitry.
Does the NCP583XV28T2G require an external capacitor on the output pin?
Yes, the NCP583XV28T2G requires a 0.1 µF ceramic capacitor on the Vout pin for stability and transient response, as confirmed in the Application Information section. A 1.0 µF ceramic capacitor is recommended on Vin. Both capacitors must be low-ESR types and placed as close as possible to their respective pins. Omitting the output capacitor risks oscillation and poor load regulation performance.
What is the function of Pin 4 (NC) on the NCP583XV28T2G SOT-563 package?
Pin 4 of the NCP583XV28T2G is marked NC (No Connect) in the Pin Function Description table and must remain unconnected - neither routed nor soldered. It is internally unconnected and serves no electrical or thermal function. Connecting Pin 4 to any net may compromise device reliability or violate the manufacturer's qualification testing conditions.
How does the enable (CE) pin logic work on the NCP583XV28T2G?
The NCP583XV28T2G features an active-high enable pin (CE). When CE voltage is ≥1.2 V (typical), the regulator powers up and delivers 2.8 V to Vout. When CE voltage drops to ≤0.3 V (typical), the device enters shutdown mode with 0.1 µA typical current draw. The CE pin draws less than 100 nA in both states, making it compatible with weak GPIO drivers or resistive divider networks.
Is the NCP583XV28T2G RoHS-compliant and halogen-free?
Yes, the NCP583XV28T2G is explicitly designated as a Pb-free device in the Ordering Information table and conforms to RoHS Directive 2011/65/EU. The packaging materials meet J-STD-609 Category 1 definition for halogen-free status, with chlorine and bromine content each below 900 ppm, as verified in onsemi's material declarations and packaging specifications.
