Product details
Overview
NCP583XV15T2G from onsemi is an ultra-low quiescent current (1.0 µA) 150 mA CMOS low-dropout regulator with enable, delivering a fixed 1.5 V output voltage in SOT-563 package. It features 250 mV dropout at 150 mA, ±2% output voltage accuracy, and operates across −40°C to +85°C ambient temperature for battery-powered portable equipment.
For engineers reviewing the NCP583XV15T2G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low Iq, tight load/line regulation, thermal performance in SOT-563, and enable-controlled shutdown current of 0.1 µA.
Technical Context
The NCP583XV15T2G integrates a precision bandgap reference, error amplifier, and PMOS pass transistor in a single-stage LDO architecture. Its CE pin enables active-high logic control with 1.2 V high-threshold and 0.3 V low-threshold, supporting low-power state transitions without external circuitry.
Designed for ceramic-capacitor stability, it achieves <20 mV load regulation (1 µA–150 mA) and 0.05%/V line regulation while maintaining 100 ppm/°C output voltage drift. Fold-back current limiting protects against short-circuit faults without requiring external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% - ensures stable core/sensor rail for low-voltage microcontrollers and analog ICs. |
| Max Output Current | 150 mA - sufficient for powering single-core MCUs, RF transceivers, or sensor signal chains. |
| Dropout Voltage | 250 mV at 150 mA - enables operation down to Vin = 1.75 V, extending battery life in single-cell Li-ion or alkaline systems. |
| Quiescent Current | 1.0 µA typical - minimizes standby power loss in always-on wearable or IoT edge nodes. |
| Shutdown Current | 0.1 µA typical - reduces system leakage during deep-sleep modes without external switches. |
| Input Voltage Range | 1.7 V to 6.0 V - supports direct connection to 2-cell alkaline, Li-ion, or regulated intermediate rails. |
| Thermal Resistance | 200 °C/W (RJA, SOT-563) - enables full 150 mA output at +85°C ambient with minimal derating. |
Pinout & Package
SOT-563 (Case 463A) is a 6-pin, 1.6 mm × 1.2 mm surface-mount package with exposed thermal pad; pin 4 is NC and must be left unconnected per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Vin) | Input power supply | Accepts 1.7–6.0 V input; requires 1.0 µF ceramic decoupling to GND per layout guidelines. |
| 2 (GND) | Power ground | Primary ground return path; connects to internal die substrate and thermal pad for heat dissipation. |
| 3 (Vout) | Regulated output | Delivers fixed 1.5 V ±2%; requires 0.1 µF ceramic capacitor close to pin for transient stability. |
| 4 (NC) | No connect | Internally unconnected; must remain floating-no routing or soldering permitted. |
| 5 (GND) | Secondary ground | Dedicated ground terminal for improved noise rejection; ties to same net as Pin 2. |
| 6 (CE) | Chip enable | Active-high logic input; drives device into 0.1 µA shutdown when pulled low (<0.3 V). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 250 mV at 150 mA enables use with weak or depleting batteries without brownout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/TT | 1.5 V fixed, 250 mA, 1.6 µA Iq, SOT-23-5; higher max current but 60% higher quiescent current. | Better suited for higher-current peripherals; less optimal for multi-year coin-cell lifetime. | Select if >150 mA peak load is required and 1.6 µA Iq remains acceptable. |
| TNIV1501502R | 1.5 V fixed, 200 mA, 0.8 µA Iq, DFN-6; slightly lower Iq but no CE pin and different pinout. | Lacks enable control-requires external MOSFET for shutdown; incompatible PCB layout. | Choose only when enable functionality is unnecessary and board redesign is feasible. |
Compared with MCP1700T-1502E/TT and TNIV1501502R, the NCP583XV15T2G uniquely balances ultra-low 1.0 µA Iq, integrated CE control, and SOT-563 space efficiency-making it optimal for compact, long-life, enable-driven portable designs where every nanoamp and square millimeter matters.

FAQ
What is the maximum input voltage rating for the NCP583XV15T2G?
The NCP583XV15T2G has an absolute maximum input voltage of 6.5 V, but its recommended operating input voltage range is 1.7 V to 6.0 V per electrical characteristics testing conditions. Exceeding 6.5 V risks permanent damage. For reliable operation in 5 V rail systems, the NCP583XV15T2G provides adequate margin while maintaining 250 mV dropout at full load.
Does the NCP583XV15T2G require an external capacitor on the output pin?
Yes-the NCP583XV15T2G requires a minimum 0.1 µF ceramic capacitor on the Vout pin for stability, with 1.0 µF recommended for optimal transient response. The datasheet specifies low-ESR X5R/X7R types placed as close as possible to the Vout and GND pins. Omitting this capacitor may cause oscillation or poor load-step recovery in the NCP583XV15T2G.
What is the function of Pin 4 (NC) on the NCP583XV15T2G SOT-563 package?
Pin 4 of the NCP583XV15T2G is explicitly designated "No Connect" (NC) in the datasheet's PIN FUNCTION DESCRIPTION table. It is internally unconnected and must remain electrically floating-no trace, pad, or solder should be attached. Violating this requirement risks unpredictable behavior or latch-up, as confirmed in the official onsemi NCP583/D datasheet Rev. 15.
How does the enable (CE) pin of the NCP583XV15T2G behave during power-up?
The NCP583XV15T2G CE pin is active-high with a 1.2 V typical threshold. During power-up, the device remains in shutdown until CE rises above 1.2 V; no external pull-up is required if driven by a clean GPIO. If CE is left floating, the internal leakage may cause undefined startup-onsemi recommends tying CE to Vin via a resistor or controlling it actively to ensure deterministic NCP583XV15T2G behavior.
Is the NCP583XV15T2G compatible with ceramic output capacitors only?
Yes-the NCP583XV15T2G is optimized for ceramic capacitors (X5R/X7R) and explicitly specifies 0.1 µF minimum capacitance with low ESR. Tantalum or aluminum electrolytic capacitors are not recommended due to higher ESR, which can degrade transient response and potentially destabilize the control loop. The NCP583XV15T2G's stability analysis assumes ceramic-type COUT per Figure 5 and Application Information section.
