MD52E18QC3

Ultra-low Power Consumption LDO MD52XX Series CMOS Voltage Regulator With ON/OFF Switch 500mA MD52XX is ultra-low power consumption low dropout voltage regulator (LDO) manufactured in CMOS processes. It can deliver up to 500mA of current while consuming only 0.6μA of quiescent current. It consists of a reference voltage generator, an error amplifier, a current foldback circuit, and a phase compensation circuit plus a driver transistor. The MD52XX is designed specifically for applications where very-low IQ is a critical parameter. This device maintains low quiescent current consumption even in dropout mode to further increase the battery life. ■ Features: ⚫ Ultra-low Quiescent Current: 0.6μA ⚫ Highly Accurate: ±2％ ⚫ Dropout Voltage: 230mV@IOUT=500mA ⚫ Maximum Output Current: 500mA ⚫ Input Voltage Range: 2.2V~7.0V ⚫ Temperature Stability: ±50ppm/℃ ⚫ ON/OFF Logic = Enable High ⚫ Standby Current: 10nA ⚫ COUT Discharge Circuit when EN Disable is Active ⚫ Protections Circuits: Current Limiter, Short Circuit, Foldback ⚫ Output Capacitor: Low ESR Ceramic Capacitor Compatible ■ Applications: ⚫ ⚫ ⚫ ⚫ Smart wearer Long-life battery-powered devices Portable mobile devices, such as mobile phones, cameras, and so on Wireless communication equipment ■ Typical Applications: VIN + EN DC - VOUT GND CIN=1.0uF + MD52XX VOUT COUT=1.0uF - MD52XX Series Ultra-Low Power Consumption LDO ■ Pin Configuration: SOT23-5L Top View SOT23-3L Top View VOUT NC VIN 5 4 3 52XX SOT89-3L(A_Type) Top View 2 52XXA 52XX 1 2 3 1 2 VIN GND EN GND VOUT 1 2 GND VIN 3 VOUT DFN1*1-4L Top View VIN EN 4 3 EP 5 1 VOUT 2 GND ■ Product Selections: Product Name VOUT (V) MD5225 MD5228 MD5230 MD5233 MD5236 MD5240 MD5250 MD5225 MD5228 MD5230 MD5233 MD5236 MD5240 MD5250 MD5225A MD5228A MD5230A MD5233A MD5236A MD5240A MD5250A MD5225 MD5228 MD5230 MD5233 2.5 2.8 3.0 3.3 3.6 4.0 5.0 2.5 2.8 3.0 3.3 3.6 4.0 5.0 2.5 2.8 3.0 3.3 3.6 4.0 5.0 2.5 2.8 3.0 3.3 Package Ordering Name SOT23-5L SOT23-5L SOT23-5L SOT23-5L SOT23-5L SOT23-5L SOT23-5L SOT23-3L SOT23-3L SOT23-3L SOT23-3L SOT23-3L SOT23-3L SOT23-3L SOT89-3L SOT89-3L SOT89-3L SOT89-3L SOT89-3L SOT89-3L SOT89-3L DFN1*1-4L DFN1*1-4L DFN1*1-4L DFN1*1-4L MD52E25QC3 MD52E28QC3 MD52E30QC3 MD52E33QC3 MD52E36QC3 MD52E40QC3 MD52E50QC3 MD52E25QA3 MD52E28QA3 MD52E30QA3 MD52E33QA3 MD52E36QA3 MD52E40QA3 MD52E50QA3 MD52A25PA1 MD52A28PA1 MD52A30PA1 MD52A33PA1 MD52A36PA1 MD52A40PA1 MD52A50PA1 MD52E25WB6 MD52E28WB6 MD52E30WB6 MD52E33WB6 2 / 14 Marking 5225 5228 5230 5233 5236 5240 5250 5225 5228 5230 5233 5236 5240 5250 5225A 5228A 5230A 5233A 5236A 5240A 5250A 5225 5228 5230 5233 Package Information Tape and Reel, 3000pcs Tape and Reel, 1000pcs Tape and Reel, 10000pcs MD52XX Series Ultra-Low Power Consumption LDO MD5236 MD5240 MD5250 3.6 4.0 5.0 DFN1*1-4L DFN1*1-4L DFN1*1-4L MD52E36WB6 MD52E40WB6 MD52E50WB6 5236 5240 5250 Tape and Reel, 10000pcs Notes: 1* Customer can request to customize the output voltage ranged from 1.2V to 5V if desired voltage is not found in the selections. 2* Customer can request customization of package choice. 3* Please pay attention to the MARKING of the product package type. ■ Absolute Maximum Ratings: PARAMETER SYMBOL Input Voltage VIN Output Voltage VOUT Power Dissipation PD Thermal Resistance RθJB (1) Operating Ambient Temperature Storage Temperature ESD Protection (Unless otherwise indicated: Ta=25℃) RATINGS UNITS -0.3 ~ 8 V Vss-0.3 ~ VIN+0.3V SOT23-5 250 SOT23-3 250 mW SOT89-3 1000 DFN1*1-4L 200 SOT23-5 180 SOT23-3 200 ℃/W SOT89-3 100 DFN1*1-4L 160 Topr -40 ~ +85 Tstg ESD HBM -40 ~ +125 6000 Note: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
