Product details
Overview
NCP582LXV15T2G from onsemi is an ultra-fast, low-noise 150 mA CMOS LDO regulator with active-low enable, delivering a fixed 1.5 V output voltage, 220 mV dropout at 150 mA, 30 µVRMS output noise (10 Hz–100 kHz), and ±2% output voltage accuracy - designed for power-sensitive portable instrumentation and imaging systems.
For engineers reviewing the NCP582LXV15T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its SOT-563 package, 75 µA quiescent current, 70 dB PSRR at 1 kHz, −40°C to +85°C operating range, and compatibility with 0.47 µF ceramic output capacitance for 1.5 V operation.
Technical Context
The NCP582LXV15T2G 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 CE pin supports system-level power sequencing and includes fold-back current limiting and thermal shutdown protection.
It operates across 2.0–6.0 V input voltage range while maintaining 1.5 V regulated output, with line regulation of 0.02%/V and load regulation of 22 mV over 1–150 mA. The device features auto-discharge disabled (active-low variant), no internal noise-reduction capacitor, and 100 ppm/°C output voltage temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% - ensures stable core/bias rail for low-voltage logic and analog sensors. |
| Max Output Current | 150 mA - sufficient for single-core microcontrollers, camera modules, and RF front-end biasing. |
| Dropout Voltage | 220 mV at 150 mA - enables operation from single Li-ion or two NiMH cells with margin. |
| Quiescent Current | 75 µA typical - minimizes battery drain in always-on monitoring and standby modes. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO. |
| Output Noise | 30 µVRMS (10 Hz–100 kHz) - suitable for noise-sensitive ADC references and RF synthesizer supplies. |
| Operating Temp | −40°C to +85°C - qualified for industrial portable equipment and outdoor handheld instrumentation. |
| Input Voltage Range | 2.0 V to 6.0 V - compatible with wide-input battery and adapter sources without external pre-regulation. |
Pinout & Package
SOT-563 (Case 463A) - 6-pin, 1.6 mm × 1.2 mm × 0.6 mm surface-mount package with exposed pad for thermal performance; Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Vin) | Input power supply | Accepts 2.0–6.0 V input; requires 1.0 µF ceramic decoupling capacitor to GND per layout guidelines. |
| 2 (GND) | Power ground | Primary ground return path; pin 2 and pin 5 are internally connected and must both be tied to PCB ground plane. |
| 3 (Vout) | Regulated output | Delivers fixed 1.5 V; requires 0.47 µF ceramic capacitor to GND for stability and transient response. |
| 4 (NC) | No connect | Unbonded die pad; must remain floating - no routing or solder mask opening required. |
| 5 (GND) | Power ground | Secondary ground terminal; electrically identical to pin 2 and improves thermal conduction and EMI performance. |
| 6 (CE) | Active-low chip enable | Pull low to enable regulator; high-Z or >1.5 V disables output and reduces shutdown current to ≤1.0 µA. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 220 mV at full 150 mA load - extends usable battery life by minimizing headroom loss. |
| Low-noise regulation | 30 µVRMS without external bypass - eliminates need for noise-reduction capacitors in space-constrained designs. |
| High PSRR | 70 dB at 1 kHz - maintains clean 1.5 V rail despite noisy DC-DC switching ripple on input. |
| Fast dynamic response | Load step recovery <10 µs (Iout: 1→150 mA) - prevents brownout during processor wake-up or sensor activation. |
| Thermal & current protection | Fold-back current limit + thermal shutdown - prevents damage during sustained overload or poor heatsinking. |
| Precision output | ±2% initial accuracy + 100 ppm/°C drift - ensures consistent performance across temperature in calibration-critical 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-1502E/TT | 250 mV dropout at 250 mA; 1.8 µA Iq; SOT-23-3 package (3-pin, no CE) | Lacks enable control and has higher dropout; suited for simpler always-on rails | Select when minimal quiescent current dominates over enable functionality and load current stays ≤100 mA. |
| Torex XC6206P152MR-G | 300 mV dropout at 150 mA; 12 µA Iq; SOT-23-5 with active-high CE | Higher dropout and lower PSRR (60 dB @ 1 kHz); no auto-discharge support | Choose for cost-sensitive designs where 1.5 V accuracy and basic enable suffice, but fast transient response is non-critical. |
Compared with MCP1700T-1502E/TT and XC6206P152MR-G, the NCP582LXV15T2G delivers superior noise performance, tighter output accuracy, and faster load transient recovery - making it optimal for precision analog and mixed-signal portable systems where rail cleanliness and dynamic behavior are critical.

FAQ
What is the maximum input voltage rating for the NCP582LXV15T2G?
The NCP582LXV15T2G has a maximum input voltage rating of 6.5 V, with recommended operating input range specified as 2.0 V to 6.0 V. Exceeding 6.5 V may cause permanent damage. This rating allows safe operation from common battery sources including two-cell alkaline (3.2 V), single Li-ion (4.2 V max), or regulated 5 V USB supplies.
Does the NCP582LXV15T2G require an external noise-reduction capacitor?
No, the NCP582LXV15T2G achieves 30 µVRMS output noise (10 Hz–100 kHz) without any external noise-reduction capacitor. Its internal design eliminates the need for a CNR pin or bypass capacitor, simplifying layout and reducing BOM count - a key advantage over many competing LDOs that mandate external capacitors for low-noise operation.
What is the function of Pin 4 (NC) on the NCP582LXV15T2G SOT-563 package?
Pin 4 on the NCP582LXV15T2G is a no-connect (NC) terminal - it is not bonded to the die and serves no electrical function. Per onsemi's datasheet and package drawings, this pin must remain unconnected on the PCB; no trace, solder mask opening, or thermal pad should be assigned to it to avoid unintended coupling or assembly issues.
How does the active-low CE pin behave during shutdown?
When the CE pin of the NCP582LXV15T2G is pulled high (>1.5 V), the device enters shutdown mode with output disabled and shutdown current ≤1.0 µA. Pulling CE low (≤0.3 V) enables regulation. Unlike the active-high auto-discharge variants, the NCP582LXV15T2G does not include internal discharge FET - Vout remains floating after disable unless externally discharged.
What ceramic capacitor value is recommended for the output of the NCP582LXV15T2G?
For the NCP582LXV15T2G delivering 1.5 V output, a 0.47 µF X5R or X7R ceramic capacitor is recommended between Vout and GND. This value ensures stability, adequate transient response, and compatibility with the device's internal compensation - confirmed in the datasheet's "Output Decoupling" section and validated across temperature and load conditions.
