Product details
Overview
NX1117CE15Z,115 from NXP Semiconductors is a fixed-output 1.5 V low-dropout linear voltage regulator in SOT223 package, delivering up to 1 A output current with ±1.25 % output voltage accuracy over −40 °C to 125 °C, featuring thermal shutdown, SOA control, and output current limiting. It serves as a post-regulator for DC-DC converters in USB-powered industrial equipment.
For engineers reviewing the NX1117CE15Z,115 datasheet, NX1117CE15Z,115 pinout, NX1117CE15Z,115 application, or NX1117CE15Z,115 equivalent, key selection criteria include dropout voltage at 800 mA (1.2 V max), PSRR of 69 dB at 120 Hz, quiescent current of 5–6 mA, and compatibility with standard 680 nF input/output capacitors.
Technical Context
The NX1117CE15Z,115 implements internal reference-based feedback with adjustable current (52–120 µA) only in ADJ variants - this fixed 1.5 V version uses trimmed resistor network for output setting. Its Safe Operating Area (SOA) control dynamically limits output current under high VIN−VOUT conditions to prevent thermal runaway.
Thermal protection activates at 135 °C junction temperature, and the device operates across 2.9 V to 11.5 V input range while maintaining regulation down to 0 mA load. Dropout voltage rises predictably from 0.95 V at 100 mA to 1.2 V at 800 mA, enabling stable operation in battery-fed systems with diminishing supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.500 V ±1.25 % (1.462–1.538 V over full temp/load range) |
| Max Output Current | 1 A continuous; current limiting engages above 1.0 A to protect against shorts |
| Dropout Voltage | 1.2 V max at 800 mA - enables regulation with only 2.7 V input at full load |
| PSRR | 69 dB at 120 Hz - suppresses ripple from upstream switching converters |
| Quiescent Current | 5–6 mA - stable across 2.9–11.5 V input, enabling low-power standby modes |
| Operating Temp | −40 °C to +125 °C ambient - qualified for industrial and automotive under-hood use |
| Thermal Shutdown | Activates at 135 °C junction temperature - prevents permanent damage during overload |
Pinout & Package
The NX1117CE15Z,115 is housed in a plastic SOT223 (SC-73) surface-mount package with integrated heat sink pad, rated for 150 K/W thermal resistance in free air and 72 K/W on FR4 PCB with 6 cm² copper pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference and thermal path - must be connected to large copper pour for thermal performance |
| 2 | VOUT | Regulated 1.5 V output - requires ≥680 nF ceramic capacitor with ≤1 Ω ESR for stability |
| 3 | VIN | Input supply (2.9–11.5 V) - must exceed VOUT by ≥1.2 V at full load to maintain regulation |
| 4 | VOUT | Second output connection - tied internally to Pin 2; used for high-current routing and thermal conduction |
Key Features
| Feature | Design Value |
|---|---|
| No minimum load requirement | Stable regulation from 0 mA to 1 A - eliminates need for dummy loads in low-power sleep states |
| SOA control | Automatically reduces current limit when VIN−VOUT exceeds safe power dissipation threshold |
| Wide input range | Operates from 2.9 V to 20 V absolute max - supports 3.3 V, 5 V, and 12 V input rails |
| Robust ESD rating | 2 kV HBM / 400 V MM - withstands handling and board-level electrostatic events |
| Low output noise | 0.003 % RMS (10 Hz–10 kHz) - suitable for noise-sensitive analog circuitry like ADC references |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-15CDCR | ±1 % accuracy, 1.2 V dropout at 800 mA, 800 mA max output, SOT-223 | Lower output current and tighter accuracy - suited for lower-power 1.5 V logic rails | Select when ±1 % tolerance is required and load stays ≤800 mA; verify thermal margin on FR4 |
| LD1117S15TR | ±2 % accuracy, 1.1 V dropout at 800 mA, 1 A output, SOT-223, no SOA control | Lacks SOA protection - requires external current limiting for high VIN−VOUT conditions | Choose for cost-sensitive designs where input differential stays ≤4 V and thermal design is conservative |
Compared with TLV1117-15CDCR, NX1117CE15Z,115 delivers higher output current (1 A vs. 800 mA) and built-in SOA control; versus LD1117S15TR, it adds robust thermal and current protection but trades ±1.25 % accuracy for ±2 %.

FAQ
What is the maximum input voltage for NX1117CE15Z,115?
The absolute maximum input voltage for NX1117CE15Z,115 is 20 V per the limiting values table. However, the recommended operating condition specifies a maximum of 11.5 V for reliable regulation at full 1 A load with 1.5 V output - exceeding this risks excessive power dissipation and thermal shutdown activation.
Does NX1117CE15Z,115 require an output capacitor?
Yes, NX1117CE15Z,115 requires a minimum 680 nF ceramic output capacitor with ≤1 Ω ESR, placed as close as possible to the VOUT pins. Omitting or undersizing this capacitor causes instability, oscillation, or poor transient response - confirmed in the "Application information" section of the datasheet.
How does SOA control function in NX1117CE15Z,115?
SOA control in NX1117CE15Z,115 dynamically reduces the output current limit when the voltage difference between VIN and VOUT exceeds safe power-handling thresholds. This prevents thermal runaway during high-differential-voltage conditions - a feature not present in basic LDOs like LD1117S15TR.
Is NX1117CE15Z,115 compatible with lead-free reflow soldering?
Yes, NX1117CE15Z,115 is qualified for lead-free reflow soldering per JEDEC J-STD-020. The SOT223 package supports peak reflow temperatures up to 260 °C, and the recommended footprint (Figure 22) includes thermal relief pads to manage heat transfer during assembly.
What is the typical PSRR performance of NX1117CE15Z,115 at 1 kHz?
The datasheet specifies PSRR only at 120 Hz (69 dB) for NX1117CE15Z,115. No guaranteed PSRR value is provided at 1 kHz; Figure 14 shows typical PSRR degrading to ~50 dB at 1 kHz for similar NX1117CE variants - designers should verify performance empirically if high-frequency ripple rejection is critical.
