Product details
Overview
NCP600SN150T1G from onsemi is a fixed-output 1.5 V, 150 mA low-dropout (LDO) linear regulator in TSOP-5 package, featuring 150 mV dropout at full load, ±2% output voltage tolerance over −40 °C to +125 °C, and 50 µVRMS output noise - designed for noise-sensitive portable battery-powered systems such as camera modules and RF front-ends.
For engineers reviewing the NCP600SN150T1G datasheet, pinout, applications, or equivalent options, key selection considerations include its ultra-low dropout under 150 mA load, fast 15 µs enable turn-on time, compatibility with low-ESR ceramic capacitors, and thermal shutdown protection at 175 °C.
Technical Context
The NCP600SN150T1G implements a PMOS pass transistor architecture enabling low dropout and high PSRR (62 dB at 120 Hz). It operates across 1.75 V to 6.0 V input range and maintains regulation down to VIN = VOUT + VDO, where VDO = 150 mV at 150 mA for the 1.5 V variant.
Its enable input (logic-high active) supports low-quiescent disable current (≤1.0 µA), while internal thermal shutdown (175 °C trip, 10 °C hysteresis) and current limiting (550 mA typical short-circuit current) provide robust fault protection without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% over −40 °C to +125 °C - ensures stable core/bias rail for low-voltage analog and digital ICs. |
| Max Output Current | 150 mA continuous - sufficient for powering single-core microcontrollers, sensors, or RF ICs in compact portable devices. |
| Dropout Voltage | 150 mV at 150 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (up to 3.2 V) with margin. |
| Noise Voltage | 50 µVRMS (10 Hz–100 kHz) - eliminates need for external bypass capacitor in VCO/RF supply chains. |
| Enable Turn-On Time | 15 µs - supports rapid power sequencing in multi-rail systems and low-latency wake-up applications. |
| PSRR | 62 dB @ 120 Hz - suppresses switching noise from upstream DC-DC converters in SMPS post-regulation. |
| Thermal Shutdown | 175 °C with 10 °C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
Package: TSOP-5 (Case 483), 3.00 × 1.50 × 0.95 mm, Pb-free, moisture sensitivity level MSL1/260.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Positive power supply input | Accepts 1.75 V to 6.0 V; must be decoupled with ≥1.0 µF ceramic capacitor near pin. |
| 2 - GND | Power ground / substrate connection | Primary return path for input/output current; connects to exposed pad in DFN variants (not present in TSOP-5). |
| 3 - ENABLE | Logic-high active enable control | Pull ≥0.9 V to activate; ≤0.4 V disables regulator and reduces ground current to ≤1.0 µA. |
| 4 - VOUT | Regulated 1.5 V output | Delivers up to 150 mA; requires ≥1.0 µF ceramic output capacitor for stability and transient response. |
| 5 - NC | No connection (fixed-voltage version) | Not bonded internally; PCB trace may be routed but must remain unconnected per datasheet Note 1. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 150 mV at 150 mA enables use with marginal input voltages - critical for battery runtime extension in wearables. |
| Low-noise regulation | 50 µVRMS noise without bypass cap simplifies layout and reduces BOM count in RF/analog signal chains. |
| Fast enable response | 15 µs turn-on time supports dynamic power gating in energy-harvesting and ultra-low-power IoT nodes. |
| Thermal & current protection | Integrated 175 °C shutdown and 550 mA current limit eliminate need for external fault management circuitry. |
| Ceramic capacitor compatible | Stable with 1.0 µF–10 µF ceramic output caps - avoids costly tantalum or polymer alternatives. |

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 | 150 mA, 1.5 V fixed, 175 mV dropout (typ), SOT-23-5 package, 65 µVRMS noise | Higher dropout and noise; lacks thermal hysteresis spec | Acceptable where board space permits SOT-23-5 and 15 µs enable timing is non-critical. |
| TPS7A0515PDBVR | 200 mA, 1.5 V fixed, 170 mV dropout (typ), SOT-23-5, 30 µVRMS noise, 5 µs enable | Lower noise, faster enable, higher current - but requires 2.2 µF min Cout and has tighter input UVLO | Preferred for new designs needing lower noise or faster wake-up; verify stability with 2.2 µF ceramic cap. |
Compared with MCP1700T-1502E/TT and TPS7A0515PDBVR, the NCP600SN150T1G offers the lowest dropout (150 mV) in TSOP-5, optimal for ultra-low-input-voltage battery operation, while maintaining industry-standard 1.5 V tolerance and proven thermal robustness in portable form factors.

FAQ
What is the maximum input voltage rating for the NCP600SN150T1G?
The NCP600SN150T1G has an absolute maximum input voltage of 6.5 V. Operation above this level risks permanent damage. For reliable long-term use, the recommended operating input range is 1.75 V to 6.0 V - ensuring proper regulation across the full 1.5 V output with margin for dropout and line variation.
Does the NCP600SN150T1G require an external bypass capacitor for noise reduction?
No, the NCP600SN150T1G does not require an external bypass capacitor. Its internal design achieves 50 µVRMS output noise (10 Hz–100 kHz) without one - a key differentiator from many competing LDOs that mandate additional capacitance for low-noise performance.
What is the function of Pin 5 (NC) on the NCP600SN150T1G TSOP-5 package?
Pin 5 on the NCP600SN150T1G is explicitly designated as "No Connection" (NC) for fixed-output versions. It is not internally bonded and must remain unconnected on the PCB. Routing traces to this pin is permitted per datasheet Note 1, but electrical connection is prohibited.
How does thermal shutdown operate in the NCP600SN150T1G?
The NCP600SN150T1G incorporates internal thermal shutdown that activates at approximately 175 °C junction temperature, turning off the output. It features 10 °C hysteresis, meaning the device resumes regulation only after cooling to ~165 °C - preventing oscillatory cycling during thermal overload conditions.
Can the NCP600SN150T1G be used with ceramic output capacitors?
Yes, the NCP600SN150T1G is fully stable with ceramic output capacitors ranging from 1.0 µF to 10 µF. Unlike older LDO architectures, it imposes no minimum ESR requirement - simplifying design, reducing cost, and improving transient response compared to tantalum-based solutions.
