Product details
Overview
NCP699SN13T1G from onsemi is a fixed-output CMOS low-dropout (LDO) regulator delivering 1.3 V at up to 150 mA, featuring 40 µA typical ground current, 340 mV dropout at full load, ±2.0% output voltage accuracy, and operation across −40 °C to +85 °C - designed for battery-powered handheld instruments requiring ultra-low quiescent power.
For engineers reviewing the NCP699SN13T1G datasheet, pinout, applications, or equivalent options, key selection criteria include enable-compatible sub-1 V logic control, TSOP-5 package thermal performance (RJA = 250 °C/W), stability with 1 µF ceramic capacitors, and verified 150 mA current limit under thermal shutdown protection.
Technical Context
The NCP699SN13T1G integrates a PMOS pass transistor with internal voltage reference, error amplifier, and protection circuits including current limit and thermal shutdown. Its enable input supports active-high logic with 0.95 V turn-on threshold and 0.3 V turn-off threshold, enabling precise system-level power sequencing.
It operates with input voltages from 2.1 V to 6.0 V and maintains regulation down to a 340 mV input–output differential at 150 mA load and 3.0 V output - though for the NCP699SN13T1G (1.3 V output), dropout is specified as 800 mV (typ) / 900 mV (max) at 150 mA per Electrical Characteristics Table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.3 V ±2.0% over −40 °C to +85 °C - ensures stable core/bias rail for low-voltage microcontrollers and sensors. |
| Max Output Current | 150 mA continuous - sufficient for powering RF front-ends, display drivers, or MCU peripherals in portable devices. |
| Dropout Voltage | 800 mV typical / 900 mV max at 150 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (2.4 V min) with margin. |
| Ground Current | 40 µA typical at 1–150 mA load - minimizes battery drain during standby or light-load operation in always-on subsystems. |
| Enable Threshold | 0.95 V (turn-on), 0.3 V (turn-off) - compatible with 1.2 V/1.8 V I/O domains and allows direct interfacing with low-voltage GPIOs. |
| Capacitor Stability | Stable with ≥1 µF ceramic or tantalum output capacitor - eliminates need for high-ESR electrolytics and reduces BOM cost/size. |
| Thermal Protection | Internal shutdown at ~160 °C junction temperature - prevents damage during sustained overload or poor PCB thermal design. |
Pinout & Package
Package: TSOP-5 (Case 483), 3.00 mm × 1.50 mm × 0.95 mm, Pb-free, surface-mount - optimized for space-constrained portable PCBs with standard reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vin | Positive input supply (2.1–6.0 V); requires local 1 µF decoupling to suppress noise and support line transients. |
| 2 | Gnd | Power ground reference; must connect to low-impedance PCB plane to maintain regulation accuracy and thermal performance. |
| 3 | Enable | Active-high digital control input; pulled to Vin if unused; enables zero-current shutdown mode when driven low. |
| 4 | N/C | No internal connection - must remain unconnected; not a test pad or thermal pad. |
| 5 | Vout | Regulated 1.3 V output; requires ≥1 µF ceramic capacitor placed adjacent to pin for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ground current | 40 µA typical across full load range - extends battery life in sleep-mode applications without sacrificing startup speed. |
| Sub-1 V enable compatibility | 0.95 V logic-high threshold - interfaces directly with 1.2 V FPGA I/O banks or advanced microcontroller GPIOs. |
| Low-noise regulation | 100 µVRMS output noise (100 Hz–100 kHz) - suitable for powering analog sensor signal chains and ADC references. |
| Wide input voltage range | 2.1 V to 6.0 V operation - supports single-cell Li-ion, dual-cell NiMH, or regulated 3.3/5.0 V system rails. |
| Robust ESD protection | 2000 V HBM per MIL-STD-883 - enhances reliability in handheld assembly and end-user handling environments. |

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 output, 250 mA rating, 1.6 µA quiescent current, SOT-23-3 package (no enable) | Lacks enable pin and thermal shutdown; lower IQ but no active control or fault protection | Select when minimal quiescent current dominates over system-level power sequencing and safety requirements. |
| TCS2115-1.3VDBVR | 1.3 V output, 200 mA, 50 µA IQ, SOT-23-5 with enable, ±1.5% accuracy, 450 mV dropout @ 150 mA | Lower dropout and tighter accuracy, but higher ground current and narrower input range (1.8–5.5 V) | Select when operating from lower-input sources (e.g., 2.5 V rails) and tighter regulation tolerance is critical. |
Compared with MCP1700T-1302E/TT and TCS2115-1.3VDBVR, the NCP699SN13T1G offers balanced trade-offs: robust enable control, integrated thermal/current protection, and proven stability with low-cost 1 µF ceramics - making it preferable for production-grade portable instrumentation where reliability and design simplicity are prioritized over marginal IQ or dropout reduction.

FAQ
What is the maximum input voltage rating for the NCP699SN13T1G?
The NCP699SN13T1G has an absolute maximum input voltage (Vin) rating of 6.0 V, with recommended operating range from 2.1 V to 6.0 V. Exceeding 6.0 V may cause permanent damage. The device is rated for 150 mA output at 1.3 V, so input-to-output differential must remain within safe power dissipation limits - e.g., at 6.0 V input, power dissipation reaches ~705 mW, requiring careful thermal design per RJA = 250 °C/W.
Does the NCP699SN13T1G require an external pull-up resistor on the Enable pin?
No, the NCP699SN13T1G does not require an external pull-up resistor on the Enable pin. If unused, the datasheet explicitly states that Enable should be connected directly to Vin to ensure default operation. The internal structure supports direct tie-to-rail use, and adding a pull-up resistor introduces unnecessary leakage path and board area - especially critical in space-constrained portable designs where the NCP699SN13T1G is commonly deployed.
Can the NCP699SN13T1G operate stably with a 0.47 µF ceramic output capacitor?
No - the NCP699SN13T1G requires a minimum 1.0 µF ceramic or tantalum output capacitor for guaranteed stability, as confirmed in both the Applications Information and Typical Application Diagram sections of the datasheet. Using 0.47 µF risks oscillation, degraded load transient response, and potential regulation failure under dynamic load conditions - particularly relevant in portable medical sensors and wearables where consistent 1.3 V rail integrity is essential.
What is the thermal shutdown trigger temperature for the NCP699SN13T1G?
The NCP699SN13T1G activates internal thermal shutdown at approximately 160 °C junction temperature, as defined in the Definitions section of the datasheet. This protection is independent of ambient temperature and load, and recovery occurs automatically once junction temperature falls below the hysteresis threshold (~140–150 °C). The shutdown mechanism safeguards against irreversible damage during sustained overload or inadequate PCB copper area - a key reliability feature for handheld instruments where thermal margin is limited.
Is the NCP699SN13T1G pin-compatible with other variants in the NCP699 family?
Yes - all NCP699 variants, including NCP699SN13T1G, NCP699SN14T1G, and NCP699SN15T1G, share identical TSOP-5 (Case 483) pinout and footprint. Pin 1 = Vin, Pin 2 = Gnd, Pin 3 = Enable, Pin 4 = N/C, Pin 5 = Vout. This allows drop-in replacement across output voltage options during prototyping or BOM optimization, provided input voltage headroom and load requirements remain compatible with the new VOUT specification.
