1-1-1 Linear Regulator ICs
SI-3000LLSL Series Surface-Mount, Low Current Consumption, Low Dropout Voltage Linear Regulator ICs
■Features
■Absolute Maximum Ratings
• Low input voltage (1.3V) and low output
voltage (1.0V)
• Compact surface-mount package (SOP8)
• Low dropout voltage: VDIF ≤ 0.3V (at IO = 1.5A)
• Built-in overcurrent, input-overvoltage and
thermal protection circuits
• Built-in ON/OFF function (OFF state circuit
current: 1µA max.)
• Compatible with low ESR capacitors

*1: IS1 is specified at the 5% drop point of output voltage VO on the condition that VIN = overcurrent protection starting current, IO = 10 mA.
*2: Output is OFF when the output control terminal (VC terminal) is open. Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs.
