LM317
12.5.1. General
Description
The LM117/LM217/LM317 are monolithic integrated circuit in TO-220, ISOWATT220, TO-3 and D
2
PAK packages intended for use as positive adjustable voltage regulators.
They are designed to supply more than 1.5A of load current with an output voltage adjustable over a
1.2 to 37V range.
The nominal output voltage is selected by means of only a resistive divider, making the device
exceptionally easy to use and eliminating the stocking of many fixed regulators.
12.5.2. Features
• Output voltage range : 1.2 To 37V
• Output current In excess of 1.5A
• 0.1% Line and Load Regulation
• Floating Operation for High Voltages
• Complete Series of Protections : Current Limiting, Thermal Shutdown And Soa Control

ST24LC21
12.6.1. Description
The ST24LC21 is a 1K bit electrically erasable programmable memory (EEPROM), organized by 8 bits.
This device can operate in two modes: Transmit Only mode and I
2
C bidirectional mode. When powered,
the device is in Transmit Only mode with EEPROM data clocked out from the rising edge of the signal
applied on VCLK. The device will switch to the I
2
C bidirectional mode upon the falling edge of the signal
applied on SCL pin. The ST24LC21 can not switch from the I
2
C bidirectional mode to the Transmit Only
mode (except when the power supply is removed). The device operates with a power supply value as
low as 2.5V. Both Plastic Dual-in-Line and Plastic Small Outline packages are available.
12.6.2. Features
• 1 million Erase/Write cycles
• 40 years data retention
• 2.5V To 5.5V single supply voltage
• 400k Hz compatibility over the full range of supply voltage
• Two wire serial interface I
2
C bus compatible
• Page Write (Up To 8 Bytes)
• Byte, random and sequential read modes
• Self timed programming cycle
• Automatic address incrementing
• Enhanced ESD/Latch up
• Performances
