Product details
Overview
NCP600SN500T1G from onsemi is a fixed-output 5.0 V, 150 mA low-dropout (LDO) linear regulator in TSOP-5 package, featuring 75 mV dropout at 150 mA, ±2% output voltage tolerance over −40 °C to +125 °C, and 50 µVrms output noise - designed for post-regulation in battery-powered instrumentation and noise-sensitive RF circuits.
For engineers reviewing the NCP600SN500T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout performance at full load, thermal resistance in TSOP-5 (215 °C/W), enable threshold stability across temperature, and compatibility with 1.0 µF ceramic output capacitors without ESR requirements.
Technical Context
The NCP600SN500T1G implements a PNP pass transistor architecture enabling ultra-low dropout and fast 15 µs enable turn-on time. It integrates thermal shutdown (175 °C trip, 10 °C hysteresis) and current limiting (300–800 mA), with internal biasing optimized for stable operation under no-load and light-load conditions.
As a fixed-voltage variant, it uses NC on the ADJ pin and requires no external resistors. Its ground current remains stable at 145 µA (typ.) across 1–150 mA load and −40 °C to +125 °C, supporting low-power portable systems where quiescent current impacts battery life.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% over −40 °C to +125 °C - ensures stable MCU core or analog supply without trimming. |
| Max Output Current | 150 mA continuous - sufficient for microcontrollers, sensors, and RF front-end biasing in handheld devices. |
| Dropout Voltage | 75 mV at 150 mA - enables regulation from 5.075 V input, critical for single-cell Li-ion or 5 V rail margining. |
| PSRR | 62 dB at 120 Hz - suppresses switching noise from upstream DC/DC converters in SMPS post-regulation. |
| Output Noise | 50 µVrms (10 Hz–100 kHz) - meets VCO and RF LNA supply noise requirements without bypass capacitor. |
| Enable Threshold | VTH(HI) = 0.9 V, VTH(LO) = 0.4 V - compatible with 1.8 V/3.3 V logic and supports direct connection to Vin if unused. |
| Thermal Resistance | RJA = 215 °C/W (TSOP-5) - limits power dissipation to ~870 mW at TA = 25 °C before thermal shutdown activates. |
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; minimum input = VOUT + VDO = 5.075 V at full load. |
| 2 - GND | Power supply ground | Device substrate reference; must be low-impedance connection to minimize noise coupling. |
| 3 - ENABLE | Logic-controlled enable input | Pull <0.4 V to disable (IDIS ≤ 1.0 µA); connect to VIN for always-on operation. |
| 4 - VOUT | Regulated 5.0 V output | Delivers up to 150 mA; stable with ≥1.0 µF ceramic capacitor; no ESR requirement. |
| 5 - ADJ/NC | No-connect (fixed-voltage version) | Internally tied; must remain unconnected - not used for feedback or adjustment. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 75 mV at 150 mA enables operation from marginal input rails common in portable designs. |
| Fast enable response | 15 µs turn-on time supports dynamic power sequencing in multi-rail systems. |
| Low-noise regulation | 50 µVrms noise eliminates need for external noise-reduction capacitors in RF/analog stages. |
| Thermal protection | 175 °C shutdown with 10 °C hysteresis prevents damage during sustained overload or poor PCB cooling. |
| Stable with ceramic caps | Works with 1.0 µF–10 µF X5R/X7R ceramics - reduces BOM count and board space vs. tantalum alternatives. |
Applications
| Portable Instrumentation Power | RF Front-End Bias 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-5002E/TT | 500 mA max output, 175 mV dropout at 250 mA, SOT-23-5 package, 65 µVrms noise | Higher current capability but larger dropout and higher noise - suitable where load exceeds 150 mA | Select when >150 mA output or smaller footprint (SOT-23) is required; verify thermal derating at full load. |
| TLC7705IPK | 100 mA max output, 350 mV dropout at 100 mA, TSOP-5, 30 µVrms noise, integrated reset delay | Lower noise but lower current and higher dropout - better for ultra-low-noise sub-100 mA analog rails | Prefer for noise-critical analog sections with <100 mA loads; avoid for digital loads requiring >150 mA. |
Compared with MCP1700T-5002E/TT and TLC7705IPK, the NCP600SN500T1G delivers optimal balance of low dropout (75 mV), moderate output current (150 mA), and industry-standard TSOP-5 thermal performance - making it ideal for cost-sensitive, space-constrained 5 V post-regulation where 150 mA is the design target.

FAQ
What is the maximum input voltage rating for the NCP600SN500T1G?
The NCP600SN500T1G has an absolute maximum input voltage of 6.5 V. Operation above this level risks permanent damage. For reliable continuous operation, the recommended maximum input is 6.0 V, as specified in the Operating Ranges table - ensuring safe margin against transients while maintaining regulation at 5.0 V output.
Does the NCP600SN500T1G require an external bypass capacitor for noise reduction?
No, the NCP600SN500T1G does not require an external bypass capacitor for noise reduction. Its internal design achieves 50 µVrms output noise (10 Hz–100 kHz) without one - unlike many competing LDOs that mandate a 10 nF–100 nF capacitor on the ADJ or NR pin. This simplifies layout and reduces BOM count.
Can the NCP600SN500T1G be used with ceramic output capacitors?
Yes, the NCP600SN500T1G is fully stable with ceramic output capacitors ranging from 1.0 µF to 10 µF, including X5R and X7R dielectrics. It imposes no minimum ESR requirement - eliminating the need for bulkier, less reliable tantalum or aluminum electrolytic capacitors in space-constrained designs.
What happens to the output voltage of the NCP600SN500T1G when the ENABLE pin is pulled low?
When the ENABLE pin is pulled below 0.4 V, the NCP600SN500T1G enters low-power standby mode: output is disabled, ground current drops to ≤1.0 µA, and VOUT floats near 0 V (not actively discharged). The device retains its ability to respond to subsequent enable transitions within 15 µs - ideal for dynamic power gating.
Is the NCP600SN500T1G still in active production according to onsemi documentation?
Yes, the NCP600SN500T1G remains active and available in TSOP-5 packaging per onsemi's official ordering information (page 13 of NCP600/D Rev. 12). Unlike several other variants (e.g., NCP600SN330T1G), the NCP600SN500T1G is explicitly listed without "DISCONTINUED" notation and ships in 3000-piece tape-and-reel format.
