Product details
Overview
NCP600SN280T1G from onsemi is a fixed-output 2.8 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 RF and portable battery-powered systems including camcorders and handheld instrumentation.
For engineers reviewing the NCP600SN280T1G datasheet, pinout, applications, or equivalent options, key selection considerations include its ultra-low dropout performance at 150 mA, fast 15 µs enable turn-on time, thermal shutdown at 175 °C, compatibility with low-ESR ceramic capacitors, and Pb-free TSOP-5 packaging with 0.95 mm profile.
Technical Context
The NCP600SN280T1G implements a PMOS pass transistor architecture enabling ultra-low dropout operation without requiring external compensation. Its internal bandgap reference and error amplifier deliver high DC accuracy and excellent line/load regulation - 1.0 mV line regulation and 2.0 mV load regulation across full temperature range.
It integrates logic-level enable control with 0.9 V rising-edge threshold and 0.4 V falling-edge threshold, plus thermal shutdown with 10 °C hysteresis and current limiting (550 mA typical short-circuit current). The device operates from 1.75 V to 6.0 V input and maintains regulation down to VOUT + VDO, where VDO = 75 mV at 2.8 V output and 150 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±2% over −40 °C to +125 °C - ensures stable bias for RF VCOs and precision analog circuitry without external resistors. |
| Max Output Current | 150 mA continuous - supports moderate-power microcontrollers, sensors, and interface ICs in space-constrained portable designs. |
| Dropout Voltage | 75 mV at 150 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (3.2 V min) with margin. |
| Noise Voltage | 50 µVRMS (10 Hz–100 kHz) - eliminates need for external bypass capacitor in sensitive RF/PLL applications. |
| Enable Turn-On Time | 15 µs - supports rapid power sequencing in multi-rail systems and low-power wake-up scenarios. |
| Thermal Shutdown | 175 °C activation with 10 °C hysteresis - protects against sustained overload or poor PCB thermal design without latch-up. |
| Ground Current | 140 µA typical at 150 mA load - minimizes quiescent power loss in always-on subsystems. |
Pinout & Package
Package: TSOP-5 (Case 483), 3.00 × 1.50 × 0.95 mm, Pb-free, surface-mount. Exposed pad not present; standard plastic leadframe construction.
| 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 placed adjacent to pin. |
| 2 - GND | Power ground reference | Primary return path for load and internal bias currents; requires low-impedance PCB trace to minimize noise coupling. |
| 3 - ENABLE | Logic-controlled on/off input | Pulled high to VIN for always-on operation; driven low (<0.4 V) to reduce ground current to 0.01 µA in shutdown mode. |
| 4 - VOUT | Regulated output terminal | Delivers 2.8 V ±2% to load; requires ≥1.0 µF ceramic output capacitor for stability and transient response. |
| 5 - NC | No connection | Internally unconnected; PCB trace may be routed but must remain floating - no electrical function or thermal benefit. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 75 mV at 150 mA enables use with marginal input sources (e.g., aging batteries or post-DC/DC rails). |
| Low-noise regulation | 50 µVRMS noise without bypass capacitor simplifies layout and reduces BOM count in RF front-ends. |
| Fast enable response | 15 µs turn-on time supports dynamic power gating in real-time embedded systems and sensor wake-up cycles. |
| High accuracy | ±2% output tolerance over full temperature and load range eliminates need for post-production calibration. |
| Robust protection | Integrated thermal shutdown (175 °C), current limit (~550 mA), and ESD rating (3.5 kV HBM) enhance field reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2802E/TT | 250 mV dropout at 250 mA; 6 µA quiescent current; SOT-23-5 package | Lower IQ suits ultra-low-power sleep modes; higher dropout limits use with weak input sources | Select when standby current <10 µA is critical and input headroom >300 mV is available. |
| Torex XC6206P282MR-G | 120 mV dropout at 150 mA; 1.0 µA shutdown current; SOT-25 package | Higher PSRR (70 dB @ 1 kHz); tighter ±1% initial tolerance but wider temp drift | Prefer for higher ripple rejection in SMPS post-regulation where layout space permits SOT-25. |
Compared with MCP1700T-2802E/TT and XC6206P282MR-G, the NCP600SN280T1G delivers superior dropout performance (75 mV vs. ≥120 mV) and lower noise (50 µVRMS vs. 80–100 µVRMS) in a thermally efficient TSOP-5 package - making it optimal for compact, noise-sensitive, battery-fed RF systems.

FAQ
What is the maximum input voltage for the NCP600SN280T1G?
The NCP600SN280T1G supports 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 or violating SOA limits, especially under high load or elevated ambient temperatures. Always ensure VIN ≤ 6.0 V in normal operation to maintain reliability and parametric performance per the datasheet.
Does the NCP600SN280T1G require an external bypass capacitor for noise reduction?
No, the NCP600SN280T1G does not require an external bypass capacitor for noise reduction. Its internal design achieves 50 µVRMS output noise (10 Hz–100 kHz) without any additional capacitor. This eliminates BOM cost and board space typically needed for low-noise LDOs - a key advantage for RF and precision analog applications where the NCP600SN280T1G is deployed.
What is the thermal shutdown behavior of the NCP600SN280T1G?
The NCP600SN280T1G activates thermal shutdown at approximately 175 °C junction temperature and includes 10 °C hysteresis. When triggered, the regulator disables output and reduces ground current to ~0.01 µA. It automatically recovers once junction temperature falls below ~165 °C. This behavior is fully integrated and requires no external circuitry - protecting the NCP600SN280T1G and downstream loads during sustained overload or inadequate heatsinking.
Can the NCP600SN280T1G be used with ceramic output capacitors?
Yes, the NCP600SN280T1G is explicitly designed for stable operation with ceramic output capacitors of ≥1.0 µF. Unlike many older LDOs, it imposes no minimum ESR requirement. Ceramic capacitors improve transient response, reduce size, and enhance reliability - making them ideal for space-constrained portable applications where the NCP600SN280T1G is commonly applied.
Is the NCP600SN280T1G pin-compatible with other NCP600 variants?
Yes, all fixed-output NCP600 variants in TSOP-5 package - including NCP600SN130T1G, NCP600SN150T1G, NCP600SN180T1G, NCP600SN250T1G, NCP600SN280T1G, NCP600SN300T1G, NCP600SN350T1G, and NCP600SN500T1G - share identical pinout and footprint. This enables voltage-scaling flexibility during design-in or revision without PCB changes, provided thermal and electrical margins remain valid for the selected output voltage.
