Product details
Overview
NCP582LXV25T2G from onsemi is an ultra-fast, low-noise 150 mA CMOS low-dropout (LDO) regulator with active-low enable and auto-discharge functionality, delivering a precise 2.5 V output voltage with ±2% accuracy over −40°C to +85°C. It features 220 mV dropout at 150 mA, 30 µVRMS output noise (10 Hz–100 kHz), and 70 dB PSRR at 1 kHz-optimized for portable battery-powered systems requiring stable, clean power under dynamic load.
For engineers reviewing the NCP582LXV25T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its SOT-563 package, active-low CE logic, 75 µA quiescent current, and compatibility with 0.47 µF ceramic output capacitance for 2.5 V operation-critical for space-constrained, low-power embedded designs.
Technical Context
The NCP582LXV25T2G implements a CMOS-based LDO architecture with internal bandgap reference, error amplifier, and P-channel pass transistor, enabling ultra-low dropout and fast transient response. Its active-low enable pin (CE) directly controls internal biasing and activates auto-discharge via an integrated N-channel MOSFET when disabled.
Designed for high ripple rejection in noisy environments, it achieves 70 dB PSRR at 1 kHz and maintains <22 mV load regulation across 1–150 mA output current. The device operates from 2.0 V to 6.0 V input while sustaining 2.5 V output with 100 ppm/°C temperature coefficient and fold-back current limiting for robust short-circuit protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5 V ±2% - tightly regulated rail for MCU cores, sensors, or RF front-ends requiring stable bias. |
| Max Output Current | 150 mA - sufficient for single-core microcontrollers, low-power DSPs, or analog signal chains. |
| Dropout Voltage | 220 mV at 150 mA - enables operation down to Vin = 2.72 V, extending battery life in 3 V systems. |
| Quiescent Current | 75 µA typical - minimizes standby power loss in always-on sensor nodes or wearables. |
| PSRR @ 1 kHz | 70 dB - suppresses switching noise from DC-DC converters feeding the LDO input. |
| Output Noise | 30 µVRMS (10 Hz–100 kHz) - avoids interference in precision ADCs, audio codecs, or PLL VCO supplies. |
| Enable Logic | Active-low CE with auto-discharge - ensures rapid VOUT discharge on shutdown, preventing floating bias in multi-rail systems. |
| Operating Temp | −40°C to +85°C - qualified for industrial and automotive cabin applications without derating. |
Pinout & Package
SOT-563 (Case 463A) 6-pin surface-mount package, 1.6 mm × 1.2 mm × 0.6 mm profile, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Vin) | Input power supply | Accepts 2.0–6.0 V; requires 1.0 µF ceramic decoupling capacitor placed adjacent to pin. |
| 2 (GND) | Power ground | Dedicated ground return path; must be connected to low-impedance PCB ground plane. |
| 3 (Vout) | Regulated output | Delivers 2.5 V ±2%; requires 0.47 µF ceramic capacitor with low ESR placed within 2 mm of pin. |
| 4 (NC) | No connect | Internally unconnected; must remain floating-no external connection permitted. |
| 5 (GND) | Power ground | Second ground terminal for improved thermal and noise performance; tied to same ground net as Pin 2. |
| 6 (CE) | Chip enable (active-low) | Pulls low to enable regulator; high or open disables output and activates auto-discharge path. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 220 mV at full 150 mA load enables use with partially depleted batteries or tight input-output margins. |
| Low-noise regulation | 30 µVRMS output noise eliminates need for external RC filters in sensitive analog circuits. |
| Auto-discharge function | Integrated N-channel switch discharges VOUT within microseconds of CE deassertion-prevents latch-up in sequenced power systems. |
| High PSRR | 70 dB at 1 kHz and 60 dB at 10 kHz rejects noise from upstream switching regulators without additional filtering. |
| Fast transient response | Load step recovery in <10 µs (IOUT 1 mA → 150 mA) maintains stability in burst-mode digital loads. |
| Thermal stability | 100 ppm/°C output drift ensures consistent voltage across industrial temperature range without calibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2502E/TT | 300 mV dropout at 250 mA; 1.6 µA IQ; no auto-discharge; SOT-23-5 package. | Lacks CE-controlled discharge; better for ultra-low-IQ always-on rails but unsuitable where rapid VOUT collapse is required. | Select when lowest possible quiescent current dominates over discharge control and transient performance. |
| Torex XC6206P252MR-G | 350 mV dropout at 150 mA; 1.0 µA IQ; no enable pin; SOT-23-3 package. | Fixed-enable only; no CE logic or auto-discharge; smaller footprint but no power sequencing capability. | Choose for cost-sensitive, space-constrained designs where enable control and discharge are unnecessary. |

FAQ
What is the recommended input and output capacitor configuration for NCP582LXV25T2G?
For NCP582LXV25T2G, use a 1.0 µF ceramic capacitor between Vin and GND. For the output, use 0.47 µF ceramic due to its 2.5 V nominal output (per datasheet Section "Output Decoupling"). Place both capacitors as close as possible to their respective pins with short, wide traces to minimize ESL and ensure stability under load transients.
Does NCP582LXV25T2G support active-high enable logic?
No, NCP582LXV25T2G uses active-low enable (CE). When CE is pulled low, the regulator enables; when CE is high or left floating, the device disables and activates its internal auto-discharge path. For active-high functionality, consider the pin-compatible NCP582DXV25T2G variant instead.
What is the maximum junction temperature and thermal derating behavior of NCP582LXV25T2G?
The absolute maximum junction temperature for NCP582LXV25T2G is 125°C. Its SOT-563 package has a thermal resistance θJA of approximately 220°C/W. At 150 mA output and 3.5 V input (1.0 V dropout), power dissipation is ~150 mW-resulting in ~33°C rise above ambient. Derating begins above 85°C ambient per the −40°C to +85°C operating range specification.
Can NCP582LXV25T2G be used with tantalum or aluminum electrolytic output capacitors?
No-NCP582LXV25T2G is optimized for ceramic capacitors only. The datasheet explicitly specifies ceramic types (1.0 µF for VOUT < 2.5 V, 0.47 µF for VOUT ≥ 2.5 V) and warns against using high-ESR capacitors like tantalum or aluminum electrolytics, which may cause instability or excessive output ripple due to insufficient phase margin.
How does the auto-discharge feature operate in NCP582LXV25T2G during shutdown?
When CE is driven high (or left open), NCP582LXV25T2G disables regulation and turns on an internal ~60 Ω N-channel MOSFET between VOUT and GND. This discharges the output capacitor rapidly-typically within tens of microseconds-ensuring VOUT collapses cleanly and preventing back-powering of upstream circuitry or unintended wake-up in multi-rail systems.
