GM6250 300mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Description Features GM6250 combines high accuracy with very low power consumption, and provides high output current even when the application requires extremely low input-output voltage dropout. GM6250 includes a precision voltage reference, an error correction circuit, over-temperature protection, and a current limited output driver. Fast transient response to load variations provides excellent stability under dynamic loads. GM6250 comes in SOT-23 (150mW), and SOT-89 (500mW). Maximum output current up 300mA Output voltage from 1.5V to 5.0V in 0.1V increments Output voltage accuracy : ±2% CMOS low power consumption, typically 1.0µA at VOUT = 5.0V Input stability: typically 0.2%/V Ultra low dropout voltage: 0.38V @ IOUT = 200mV at VOUT = 5.0V SOT-23 (150mW), SOT-89 (500mW) and TO-92 packages Application Palmtops Battery Powered Equipment Portable Cameras Reference Voltage Sources Video Recorders Typical Application Circuits GM6250-x.x VOUT CIN 1µF (Tantalum) VSS RL COUT 1µF (Tantalum) GM6250V2.00 VIN VIN www.gammamicro.com.tw 1 GM6250 300mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Marking Information and Pin Configurations (Top View) SOT23 VIN 2 EAVYW 1 VSS TO92 SOT89 6250 VV AYWW GM6250 VVAYWW 3 VOUT 1 VSS 1 2 3 VSS VIN VOUT EA: Device Code V: Voltage Code (see next page) Y: Year (8 = 2008, 9 = 2009 ….)

VOLTAGE REGULATOR Application Note Notes on Usage 1. It is recommended to operate the GM6250 series within the stipulated absolute maximum ratings as the IC is liable to malfunction it is operated outside the ratings. 2. There is a possibility of heat or oscillation as a result of the impedance present between the power supply and the IC's input. Where impedance is greater 10Ω, it is recommend to use a capacitor (CIN) of at least 1µF at the input terminal. 3. With a large output current, operations can be stabilized by increasing capacitor size (CIN). If CIN is too small and capacitance of (CL) is increased, there is a possibility of oscillation due to input impedance. In such case, operation can be stabilized by either increasing the size of CIN or decreasing the size of CL. 4. Please ensure the output current (IOUT) is less than Pd ÷ (VIN - VOUT) and does not exceed the stipulated continuous for total power dissipation value (Pd) for the package. CALCULATING POWER DISSIPATION The GM6250 series precision linear regulators include thermal shutdown and current limit circuitry to protect the devices. However, high power regulators normally operate at high junction temperatures so it is important to calculate the power dissipation and junction temperatures accurately to be sure that you use and adequate heat sink. The thermal characteristics of an IC depend four factors: 1. Maximum Ambient Temperature TA (℃) 2. Power Dissipation PD (Watts) 3. Maximum Junction Temperature TJ (℃) 4. Thermal Resistance Junction to ambient RJA (℃/W) These relationship of these four factors is expressed by equation : TJ = TA + PD X RJA GM6250V2.00 Maximum ambient temperature and power dissipation are determined by the design while the maximum junction temperature and thermal resistance depend on the manufacturer and the package type. 9 GM6250 300mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Output Voltage – VOUT (V) 3.1 3.0 TOPR = 25°C 2.9 2.8 2.7 0 VIN = 4V CIN = 1µF CL = 11µF 20 40 60 80 100 120 140 160 180 Input-Output Voltage Difference– VDIF (V) Typical Performance Characteristics (for GM6250-3.0) 1.0 CIN = 1µF CL = 11µF 0.8 0.6 0.4 0.2 TOPR = 25°C 0.0 -0.2 20 40 60 80 100 120 140 160 180 Output Current: IOUT (mA) Figure 2: Input/ Output Voltage differential vs. Output Current Figure 1: Output Voltage vs. Output Current 3.10 Output Voltage: VOUT (V) 3.00 IOUT=1mA 2.80 40mA 2.60 10mA TOPR = 25°C CIN=1µF CL=1µF 2.40 2.20 2.5 Output Voltage: VOUT (V) 3.20 10mA 2.95 TOPR = 25°C CIN=1µF CL=1µF 2.90 3 4 5 6 7 8 9 Input Voltage: VIN(V) Figure 3: Output Voltage vs. Input voltage Figure 4: Output Voltage vs. Input voltage 10 2.50 TOPR = 25°C Supply Current: ISS(µA) Supply Current:ISS(µA) GM6250V2.00 10 40mA Input Voltage: VIN (V) 3.0 2.0 1.0 0 IOUT=1mA 3.00 2.85 3.5 3.0 3.05 2.25 TOPR = 25°C 2.00 1.75 1.50 0 2 4 6 8 Input Voltage: VIN(V) Figure 5: Supply Current vs. Input Voltage 10 3 4 5 6 7 8 9 Input Voltage: VIN(V) Figure 6: Supply Current vs. Input Voltage 10 GM6250 300mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Typical Performance Characteristics (for GM6250-3.0, continued) 6 2 4 0 3 Output Voltage -2 2 IOUT = 1mA CL = 1µF -4 -6 Time (0.4msec/div) 1 Input Voltage 0 Figure 7: Input Transient Response 1 5 4 IOUT = 1mA CL = 1µF 1 4.0 3.5 3 2 4.5 Output Voltage 3.0 2.5 Time (1msec/div) Figure 8: Input Transient Response 2 VIN = 4VDC + 1VPPAC IOUT = 40mA CL = 1µF 50 40 30 20 10 0 0.01 0.1 1 10 Ripple Frequency: f (kHz) Figure 9: Ripple Rejection Rate GM6250V2.00 Ripple Rejection Rate :RR (dB) 60 Input Voltage – VIN (V) 5 Output Voltage – VIOUT (V) Input Voltage – VIN (V) 4 5.0 6 Input Voltage Output Voltage – VIOUT (V) 6 11 GM6250 300mA ULTRA LOW DROPOUT POSITIVE VOLTAGE REGULATOR Package Outline Dimensions – SOT 23 0.110 - 0.120 (2.80 - 3.04) 0.003 - 0.007 (0.08 - 0.18) 0.013 - 0.017 (0.34 - 0.44) 0.083 - 0.104 (2.11 - 2.62) 0.047 - 0.055 (1.20 - 1.40) 0 - 8 typ 0.075 Typ.
