Product details
Overview
NCP4620HSQ25T1G from onsemi is a 2.5 V, 150 mA CMOS low-dropout linear voltage regulator in SC-70-5 package, featuring ±1.0% output voltage accuracy, 165 mV dropout at 100 mA (VOUT = 3.3 V), and chip enable functionality for power management in space-constrained portable electronics.
For engineers reviewing the NCP4620HSQ25T1G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, thermal behavior, enable-controlled startup/shutdown timing, ceramic-capacitor stability, and real-world load/line transient performance data per ON Semiconductor's Rev. 4 datasheet.
Technical Context
The NCP4620HSQ25T1G implements a CMOS-based LDO architecture with internal reference, error amplifier, and N-channel pass transistor - enabling low quiescent current (23 µA) and high PSRR (70 dB @ 1 kHz). Its CE pin accepts TTL-compatible logic-high enable (VCEH ≥ 1.7 V) and features internal pull-down current (0.3 µA).
Thermal shutdown activates at 165°C (TTSD) with hysteresis release at 110°C (TTSR). It operates across −40°C to +85°C ambient, supports input voltages from 2.6 V to 10 V, and maintains stable regulation with 0.47 µF ceramic capacitors on both input and output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±1.0% over −40°C to +85°C - ensures precise rail generation for analog sensors or MCU cores. |
| Max Output Current | 150 mA continuous - sufficient for powering single-core microcontrollers, RF transceivers, or small display drivers. |
| Dropout Voltage | 165 mV @ IOUT = 100 mA, VOUT = 3.3 V; 400 mV @ 150 mA, VOUT = 2.8 V - enables operation from 2-cell Li-ion (≈3.0–4.2 V) with margin. |
| Quiescent Current | 23 µA typical - minimizes battery drain in always-on monitoring circuits. |
| PSRR | 70 dB @ 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Line Regulation | 0.02%/V typical - maintains tight output stability despite battery voltage sag during discharge. |
| Thermal Shutdown | Triggers at 165°C junction temperature with 55°C hysteresis - protects against sustained overload or poor PCB heat sinking. |
Pinout & Package
Package: SC-70-5 (Case 419A), 1.25 mm × 2.1 mm footprint, 0.65 mm pitch, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 2.6 V to 10 V; requires local 0.47 µF ceramic decoupling for stability and transient response. |
| GND | Ground reference | Common return path for input, output, and CE; must be low-impedance with short trace to VIN/GND capacitor pads. |
| CE | Chip enable control | Active-high logic input (VCEH ≥ 1.7 V); internal 0.3 µA pull-down allows direct tie-to-VIN if unused. |
| VOUT | Regulated output | Delivers fixed 2.5 V ±1.0%; stable with ≥0.47 µF ceramic output capacitor placed adjacent to pin. |
| NC | No connection | Unbonded die pad; electrically isolated - must remain floating, not tied to GND or any other net. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 165 mV @ 100 mA enables use with 2.6 V minimum input - critical for brownout resilience in Li-ion systems. |
| Ceramic capacitor compatibility | Stable with ≥0.47 µF X5R/X7R ceramics on input/output - eliminates need for larger, higher-ESR tantalum or aluminum electrolytics. |
| Enable-controlled power gating | CE pin reduces quiescent current to ≤1.0 µA in shutdown - extends battery life in sleep-mode applications. |
| Current fold-back protection | Limits short-circuit current to ~40 mA - prevents thermal runaway during output faults without external current-limiting resistors. |
| High PSRR at audio frequencies | 70 dB @ 1 kHz rejects ripple from buck converter switching harmonics - preserves signal integrity in ADC reference or audio bias rails. |
Applications
| Wearable Health Sensor Node | IoT Edge Device Power Rail |

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 | 250 mA output, 1.6 µA quiescent current, SOT-23-3 package (no CE pin) | Lacks enable control and thermal shutdown; lower IQ suits ultra-long-life applications where disable is unnecessary | Select when minimal quiescent current is primary and enable function is omitted from system design |
| TPS7A0525PDBVR | 200 mA output, 25 nA IQ, 170 mV dropout @ 100 mA, SOT-23-5 with CE | Lower dropout and IQ, but rated only for 5.5 V max input - unsuitable for 10 V input scenarios | Prefer for 3.3 V or lower input systems requiring lowest possible standby power and tighter dropout |
Compared with MCP1700T-2502E/TT and TPS7A0525PDBVR, the NCP4620HSQ25T1G uniquely balances 10 V input capability, integrated thermal shutdown, CE control, and SC-70 footprint - making it optimal for 2-cell Li-ion powered devices needing fault protection and compact layout.

FAQ
What is the maximum input voltage rating for the NCP4620HSQ25T1G?
The NCP4620HSQ25T1G has an absolute maximum input voltage of 12.0 V, but its recommended operating input range is 2.6 V to 10 V. Exceeding 10 V may degrade long-term reliability or trigger overvoltage stress not covered by guaranteed specifications. The NCP4620HSQ25T1G is optimized for 2-cell Li-ion (3.0–4.2 V) and 3-cell alkaline/nickel-based battery inputs.
Does the NCP4620HSQ25T1G require external components for stability?
No, the NCP4620HSQ25T1G is internally compensated and stable with ≥0.47 µF ceramic capacitors on both input and output pins. Unlike many older LDOs, it does not require ESR-tuned tantalum or electrolytic capacitors. The NCP4620HSQ25T1G achieves phase margin >60° with standard X5R/X7R MLCCs, simplifying layout and reducing BOM count.
How does the CE pin behave when left unconnected?
When the CE pin is left unconnected, the internal 0.3 µA pull-down current forces the pin to logic-low, disabling the NCP4620HSQ25T1G output. To enable operation, CE must be actively driven to ≥1.7 V (VCEH). For permanent enable, connect CE directly to VIN - the NCP4620HSQ25T1G tolerates up to 12 V on CE per absolute maximum ratings.
What is the thermal performance of the NCP4620HSQ25T1G in SC-70 package?
In SC-70-5 package, the NCP4620HSQ25T1G has a junction-to-air thermal resistance (RJA) of 263°C/W. At 150 mA output into 2.5 V with 5 V input (2.5 V dropout × 150 mA = 375 mW dissipation), junction temperature rise is ~99°C above ambient - well within the 150°C max TJ limit if ambient stays below 51°C. The NCP4620HSQ25T1G includes thermal shutdown at 165°C for safety.
Can the NCP4620HSQ25T1G be used with a 1.2 V input supply?
No - the NCP4620HSQ25T1G requires a minimum input voltage of 2.6 V to regulate 2.5 V output. With only 1.2 V input, the device cannot achieve dropout headroom and will not deliver regulated output. The NCP4620HSQ25T1G is incompatible with single-cell NiMH (1.2 V) or discharged Li-ion (<2.6 V) conditions; use a buck-boost or higher-input LDO instead.
