ME6212 High Speed LDO Regulators, High PSRR, Low noise, ME6212 Series General Description Features The ME6212 series are highly accurate, low noise,  Maximum Output Current: 350mA （VIN＝4.3V,VOUT＝3.3V） CMOS LDO Voltage Regulators. Offering low output noise, high ripple rejection ratio, low dropout and very  Dropout Voltage: 120mV@ IOUT =100mA fast turn-on times, the ME6212 series is ideal for  Operating Voltage Range: 2V～6.0V today’s cutting edge mobile phone. Internally the  Highly Accuracy: ±2％ ME6212 includes a reference voltage source, error  Low Power Consumption: 50uA（TYP.） amplifiers, driver transistors, current limiters and phase  Standby Current: 0.1uA（TPY.） compensators. The ME6212’s current limiters' foldback  High Ripple Rejection: 65dB@1KHz（ME6212C33） circuit also operates as a short protect for the output  Low output noise: 50uVrms current limiter and. the output pin. The ME6212 series is  Line Regulation: 0.05％（TYP.） also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies.The CE function allows the output of regulator to be turned off, resulting in greatly reduced power consumption. Typical Application Package  Mobile phones   Cordless phones, radio communication equipment  Portable games  Cameras, Video cameras  Reference voltage sources  Battery powered equipment V06 www.microne.com.cn 5-pin SOT23-5 Page 1 of 14 ME6212 Typical Application Circuit VIN Vout VSS ME6212 CE NC CIN 1uF Selection Guide CIN 1uF ME6212C30M5G表面丝印内容：CGXX 说明：CG是料号固定代码，XX是年月不固定 ME 62 12 X XX XX G Environment mark Package M5：SOT23-5 Output Voltage 33：3.3V …… Version or Function Product Type Product Series Microne product series Output voltage Package ME6212C12M5G 1.2V SOT23-5 ME6212C15M5G 1.5V SOT23-5 ME6212C18M5G 1.8V SOT23-5 ME6212C21M5G 2.1V SOT23-5 ME6212C25M5G 2.5V SOT23-5 ME6212C28M5G 2.8V SOT23-5 ME6212C29M5G 2.9V SOT23-5 ME6212C30M5G 3.0V SOT23-5 ME6212C33M5G 3.3V SOT23-5 ME6212C50M5G 5.0V SOT23-5 NOTE: If you need other voltage and package, please contact our sales staff。 V06 www.microne.com.cn Page 2 of 14 ME6212 Pin Configuration VOUT NC 5 4 1 2 3 VIN VSS CE SOT23-5 Pin Assignment Pin Number Pin Name Functions 1 VIN Power Input 2 VSS Ground 3 CE ON / OFF Control 4 NC No Connect 5 VOUT Output SOT23-5 Block Diagram V06 www.microne.com.cn Page 3 of 14 ME6212 Absolute Maximum Ratings Parameter Symbol Ratings Units Input Voltage VIN 6.5 V Output Current IOUT 500 mA Output Voltage VOUT Vss-0.3～VIN +0.3 V CE Pin Voltage VCE Vss-0.3～VIN +0.3 V Power Dissipation SOT23-5 PD 0.6 W Thermal resistance (Junction to air) SOT23-5 θJA 210 ℃/W Operating Ambient Temperature Range TOPR -40 ~ +85 ℃ Junction Temperature TJ -40 ~ +150 ℃ Storage Temperature Range TSTG -55 ~ +150 ℃ Electrical Characteristics ME6212C12 (VIN= VOUT+1V，VCE = VIN，CIN=CL=1uF，Ta=25OC ,unless otherwise noted) Parameter Symbol Conditions VOUT(E) IOUT=30mA, (Note 2) VIN= VOUT+1V Maximum Output Current IOUTMAX VIN= VOUT+1V Load Regulation ∆VOUT Dropout Voltage VDIF1 (Note 1) Output Voltage Min.
