Product details
Overview
NCP583XV18T2G from onsemi is an ultra-low quiescent current (1.0 µA typical), 150 mA CMOS low-dropout regulator with active-high enable, delivering a precise 1.8 V output voltage in the SOT-563 package. It features 250 mV dropout at 150 mA, ±2% output voltage accuracy, and operates across −40°C to +85°C for portable battery-powered systems requiring stable, low-power voltage regulation.
For engineers reviewing the NCP583XV18T2G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low Iq, tight load/line regulation (20 mV / 0.05%/V), thermal performance (RJA = 200°C/W), shutdown current (0.1 µA), and compatibility with 0.1 µF ceramic output capacitance.
Technical Context
The NCP583XV18T2G integrates a precision bandgap reference, error amplifier, and PMOS pass transistor in a CMOS architecture optimized for minimal static current. Its enable logic directly controls the pass device gate, enabling fast turn-on/turn-off with sub-µA shutdown leakage.
Designed for single-supply operation up to 6.5 V input, it maintains regulation down to VIN = VOUT + 0.25 V at full load and exhibits low temperature drift (±100 ppm/°C) and high ripple rejection (>50 dB at 1 kHz) with 1 µF output capacitance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1802E/TT | 1.8 V, 250 mA, 1.6 µA Iq, SOT-23-5; higher Iq, larger package, no NC pin | Higher output current margin but less space-constrained designs; lacks dual-GND configuration | Select when >150 mA peak load or simplified 5-pin layout is preferred over ultra-low Iq |
| TN0185D18R | 1.8 V, 200 mA, 0.9 µA Iq, DFN-6; slightly lower Iq, same footprint tolerance, no NC pin | Better Iq but limited thermal performance (RJA ≈ 240°C/W); not qualified for extended temperature range | Select only for commercial-temp applications where 0.1 µA Iq advantage is critical and thermal headroom exists |

FAQ
What is the maximum input voltage rating for the NCP583XV18T2G?
The NCP583XV18T2G has a maximum input voltage rating of 6.5 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable long-term use, the recommended operating input range is 1.7 V to 6.0 V, per the Electrical Characteristics section. The NCP583XV18T2G maintains regulation down to VIN = VOUT + 0.25 V, enabling efficient use of partially discharged batteries.
Does the NCP583XV18T2G require an external output capacitor, and if so, what value is recommended?
Yes, the NCP583XV18T2G requires an external ceramic output capacitor for stability. The datasheet recommends a minimum of 0.1 µF placed as close as possible to the Vout pin, with low ESR. For improved transient response and ripple suppression, a 1.0 µF ceramic capacitor is also supported. The NCP583XV18T2G is explicitly characterized and guaranteed stable with these values-no additional series resistance or specialized capacitor types are needed.
How does the enable (CE) pin function on the NCP583XV18T2G?
The CE pin on the NCP583XV18T2G is an active-high digital control input. When CE ≥ 1.2 V (typical), the regulator enables and delivers 1.8 V to Vout. When CE ≤ 0.3 V (typical), the device enters shutdown mode with only 0.1 µA typical current draw. The NCP583XV18T2G does not invert logic; no external pull-up or pull-down is required for basic operation, though system-level noise immunity may warrant a weak pull-down.
What is the thermal performance of the NCP583XV18T2G in its SOT-563 package?
The NCP583XV18T2G in the SOT-563 package has a junction-to-ambient thermal resistance (RJA) of 200°C/W, measured on a standard JEDEC 2-layer board. This allows continuous 150 mA output at +85°C ambient without exceeding the 125°C maximum junction temperature, assuming minimal PCB copper. For higher ambient or sustained loads, adding thermal vias under the exposed pad (if present in variant) or increasing copper area improves performance. The NCP583XV18T2G datasheet confirms this RJA value in the Maximum Ratings table.
Is the NCP583XV18T2G compatible with ceramic capacitors only, or can tantalum or aluminum electrolytic types be used?
The NCP583XV18T2G is characterized and guaranteed stable only with ceramic output capacitors, specifically 0.1 µF to 1.0 µF X7R or X5R dielectrics. Tantalum or aluminum electrolytic capacitors are not recommended due to their higher ESR and potential instability-these may cause oscillation or poor transient response. The NCP583XV18T2G's internal compensation is optimized for low-ESR ceramics, and the datasheet explicitly specifies ceramic types in all application circuits and test conditions.
