LA5160AM

Ordering number : ENN8319 Monolithic Linear IC LA5160AM Overview 5V/0.1A Constant-voltage Power Supply IC with Output ON/OFF Feature The LA5160AM is a general-purpose constant-voltage power supply IC incorporating the output ON/OFF function, which offers advantages such as small current drain when output OFF and saves power dissipation of the equipment. Functions & Features • Output voltage ON/OFF control with the strobe pin (active, low) • Output current of 100mA obtainable • Small current drain when output OFF and optimum for power saving • MFP8 package, ensuring easy mounting design • Full compliment of protection circuits incorporated (including overcurrent protection, thermal protection) Specifications Maximum Ratings at Ta=25°C Parameter Input Voltage Strobe Pin Voltage Allowable Power Dissipation 1 Allowable Power Dissipation 2 Operating Temperature Storage Temperature Symbol VIN max VST max Pd max1 Pd max2 Topr Tstg Independent IC * Mounted on a specified board Conditions Ratings 40 VIN max 0.3 0.8 -40 to +125 -55 to +150 Unit V V W W °C °C * Specified board: 114.3mm×76.1mm×1.6mm Board material: glass epoxy Recommended Operating Conditions at Ta=-40°C • +25°C • +125°C Parameter Input Voltage Output Current Output ON Control Voltage Output OFF Control Voltage VIN IOUT VSTL VSTH Symbol Conditions Ratings 7.5 to 20 0 to 100 -0.3 to 0.7 2.0 to VIN Unit V mA V V Any and all SANYO Semiconductor products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO Semiconductor representative nearest you before using any SANYO Semiconductor products described or contained herein in such applications. SANYO Semiconductor assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor products described or contained herein. 92706 / 61005 MH IM B8-8587 No.8319-1/6 LA5160AM Operation Characteristics at Ta=-40°C • +25°C • +125°C, unless otherwise specified, VIN=10V and IOUT=50mA in the specified test circuit Parameter Output Voltage 1 Line Regulation 1 Line Regulation 2 Load Regulation 1 Load Regulation 2 Output Voltage 2 Current Dissipation Output Noise Voltage Symbol VOUT1 ∆VOLN1 ∆VOLN2 ∆VOLD1 ∆VOLD2 VOUT2 IQ VNO Rrej1 Ripple Rejection Rrej2 Minimum I/O Voltage Difference Output ON Control Voltage Short-Circuit Current Peak Output Current Vdrop VSTL IOSC IOP VIN=35V, relative to GND 300 700 10Hz ≤ f ≤ 100kHz f=120Hz 8V≤VIN≤19V IOUT=10mA f=120Hz 8V ≤ VIN ≤ 19V IOUT=50mA IOUT=50mA 60 7V ≤ VIN ≤ 25V, IOUT=20mA 8V ≤ VIN ≤ 20V, IOUT=20mA 1mA ≤ IOUT ≤ 50mA 1mA ≤ IOUT ≤ 20mA 7V ≤ VIN ≤ 20V, 1mA ≤ IOUT ≤ 50mA 4.75 1.9 90 63 Conditions min 4.8 Ratings typ 5.0 3 1 max 5.2 50 25 100 50 5.25 5.0 V mV mV mV mV V mA µVrms dB Unit 50 54 2.0 0.7 dB V V mA mA [ VST="H" when the output is OFF ] Parameter "L" Output Voltage Quiescent Current Output OFF Control Voltage Symbol VOOFF IQOFF VSTH VST=5V Excluding VST=5V and ISTB 2.0 Conditions min Ratings typ 20 35 max 200 40 VIN mV µA V Unit Thermal protection Parameter Operating Temperature * Symbol TTSD Conditions min 150 Ratings typ 180 max °C Unit Note : The value with an asterisk mark for thermal protection is the design target value and no measurement is made.

When the STB function is not to be used, connect the STB pin to GND to ensure trouble-free operation of STB. 4) Note that wrong connection, such as connection of VIN to minus and GND to plus, may cause flow of the overcurrent.
