Product details
Overview
NCP600SN130T1G from onsemi is a fixed-output 1.3 V, 150 mA low-dropout (LDO) linear regulator in TSOP-5 package, designed for portable battery-powered systems requiring ultra-low dropout (175 mV at 150 mA), high accuracy (±2% over temperature and load), and fast enable response (15 µs). It delivers stable power to noise-sensitive analog circuits such as RF front-ends and precision sensors.
For engineers reviewing the NCP600SN130T1G datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed application use cases, and two rigorously cross-checked alternative parts with documented functional and packaging differences.
Technical Context
The NCP600SN130T1G implements a PMOS pass transistor architecture enabling ultra-low dropout voltage and excellent line/load regulation (≤10 mV and ≤20 mV respectively). Its internal bandgap reference and error amplifier maintain output stability across −40 °C to +125 °C ambient temperature with no external compensation required.
It integrates thermal shutdown (trip at 175 °C, 10 °C hysteresis) and current limiting (550 mA typical short-circuit current), and operates from 1.75 V to 6.0 V input while delivering 1.3 V ±2% output across full load (0–150 mA) and temperature range. The ENABLE pin supports logic-level control with 0.9 V turn-on threshold and <100 nA bias current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.3 V ±2% over −40 °C to +125 °C, 1.0–150 mA load - ensures stable core supply for low-voltage microcontrollers without trimming. |
| Dropout Voltage | 175 mV at 150 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (2.4 V min) with ≥1.13 V headroom. |
| Ground Current | 135 µA typical at 150 mA load - minimizes quiescent power loss in always-on subsystems like real-time clocks or sensor wake-up logic. |
| PSRR | 62 dB at 120 Hz - suppresses switching noise from upstream DC/DC converters in mixed-signal applications. |
| Enable Turn-On Time | 15 µs - supports rapid power sequencing in multi-rail systems where timing-critical peripherals require synchronized supply ramp. |
| Noise Voltage | 50 µVRMS (10 Hz–100 kHz) - eliminates need for external bypass capacitors in VCO biasing or ADC reference paths. |
| Thermal Shutdown | 175 °C junction trip with 10 °C hysteresis - protects against sustained overload or poor PCB thermal layout without external circuitry. |
Pinout & Package
Package: TSOP-5 (Case 483), 3.00 × 1.50 × 0.95 mm, Pb-free, moisture sensitivity level MSL1/260. Exposed pad not present; thermal resistance RJA = 215 °C/W on standard 1 oz copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Positive power supply input | Accepts 1.75–6.0 V; must be decoupled with ≥1.0 µF ceramic capacitor placed adjacent to pin to ensure transient stability. |
| 2 - GND | Power supply ground | Primary return path for input/output currents; connects to system ground plane with low-inductance trace to minimize noise coupling. |
| 3 - ENABLE | Logic-controlled enable input | Pulled high to VIN for always-on operation; driven low (<0.4 V) to reduce ground current to 0.01 µA for standby mode. |
| 4 - VOUT | Regulated 1.3 V output | Delivers up to 150 mA; requires ≥1.0 µF output capacitor (ceramic/tantalum) close to pin for load transient response. |
| 5 - NC | No connection (fixed-voltage version) | Not bonded internally; PCB trace may be routed but must remain unconnected to avoid parasitic coupling or ESD risk. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 175 mV at full 150 mA load - extends battery runtime in 1.8 V or lower I/O domain supplies. |
| High output accuracy | ±2% over full temperature and load range - eliminates need for post-regulation calibration in precision analog signal chains. |
| Low-noise operation | 50 µVRMS without bypass capacitor - simplifies layout for RF ICs and high-resolution ADCs by removing noise-filtering components. |
| Fast enable response | 15 µs turn-on time - meets tight power-up sequencing windows in automotive infotainment and industrial PLC modules. |
| Integrated protection | Thermal shutdown + current limit - prevents damage during output short or excessive ambient temperature without external monitoring. |
Applications
| Wireless Sensor Node Power | Low-Voltage Microcontroller Core Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1302E/TT | 1.3 V fixed, 250 mA, SOT-23-5; higher dropout (280 mV @ 250 mA), lower PSRR (55 dB @ 120 Hz) | Higher output current capability but less suitable for ultra-low-input applications or high-ripple environments | Choose when >150 mA load or smaller footprint (SOT-23 vs TSOP-5) is prioritized over dropout and noise performance |
| TPS7A0513PDBVR | 1.3 V fixed, 200 mA, SOT-23-5; lower quiescent current (25 µA), higher dropout (300 mV @ 200 mA), no thermal shutdown | Better for ultra-low-IQ always-on sensing, but lacks overtemperature protection and has poorer transient response | Prefer for battery-gauging or RTC backup rails where thermal fault coverage is non-critical and IQ dominates lifetime analysis |
Compared with MCP1700T-1302E/TT and TPS7A0513PDBVR, the NCP600SN130T1G offers superior dropout (175 mV vs ≥280 mV), higher PSRR (62 dB), and integrated thermal protection - making it optimal for space-constrained, thermally demanding, or high-ripple portable systems where 150 mA is sufficient.

FAQ
What is the maximum input voltage rating for the NCP600SN130T1G?
The NCP600SN130T1G has an absolute maximum input voltage of 6.5 V. However, its recommended operating input range is 1.75 V to 6.0 V. Operation above 6.0 V risks exceeding safe junction temperature limits and may degrade long-term reliability, even if within absolute max ratings. Always ensure VIN does not exceed 6.0 V in normal operation for the NCP600SN130T1G.
Does the NCP600SN130T1G require an external bypass capacitor for noise reduction?
No, the NCP600SN130T1G does not require an external bypass capacitor for noise reduction. Its internal architecture achieves 50 µVRMS output noise (10 Hz–100 kHz) without any additional capacitor. This eliminates board space and cost associated with external filtering while maintaining performance in noise-sensitive applications like VCO biasing - a key design advantage of the NCP600SN130T1G.
What is the function of Pin 5 (NC) on the NCP600SN130T1G TSOP-5 package?
Pin 5 on the NCP600SN130T1G is a true no-connect (NC) terminal - it is not bonded internally and serves no electrical function. Per the datasheet, printed circuit board traces may be routed beneath or near this pin, but it must remain unconnected to any net. Connecting Pin 5 risks introducing parasitic coupling or compromising ESD robustness, so it must be left floating in all designs using the NCP600SN130T1G.
How does the ENABLE pin behave when unused in the NCP600SN130T1G circuit?
When the ENABLE pin is unused in the NCP600SN130T1G, it must be tied directly to VIN to ensure continuous operation. Leaving it floating is not permitted - the datasheet specifies that the pin must be pulled to logic high (>0.9 V) for normal regulation. Connecting ENABLE to VIN guarantees the device remains active, maintains overshoot clamping, and avoids unintended shutdown due to noise or leakage.
What thermal derating applies to the NCP600SN130T1G in its TSOP-5 package?
The NCP600SN130T1G in TSOP-5 has a junction-to-ambient thermal resistance (RJA) of 215 °C/W under standard conditions (645 mm² copper area, 1 oz thickness). At 25 °C ambient and 150 mA load, power dissipation is ~105 mW, resulting in ~22.6 °C junction rise - well below the 125 °C max operating limit. For higher ambient temperatures or reduced copper area, derate output current per Equation 3 in the datasheet to keep TJ ≤ 125 °C.
