VS+ terminal: Pin Number = 1; Pin Type = Unspecified
GND terminal: Pin Number = 2; Pin Type = Unspecified
VOUT terminal: Pin Number = 3; Pin Type = Unspecified
Layout footprint: default footprint with 3 pads named VS+, VOUT, and GND; footprint text includes Z03A, which corresponds to a TO-92-style 3-lead package marking from the imported footprint data.
Datasheet state: the project had no datasheet URL accessible to the datasheet query tool. I recorded the official TI datasheet URL in project Implementation Details because no direct top-level Datasheet URL mutation was available in the accessible metadata tool.
Datasheet Key Specs for LM35CAZ/NOPB
Manufacturer: Texas Instruments
Orderable MPN: LM35CAZ/NOPB
Device family: LM35 precision centigrade temperature sensor
Package: TO-92, TI package code LP, 3 pins
Package body size: approximately 4.30 mm × 4.30 mm nominal
Temperature range for LM35CAZ/NOPB: −40°C to +110°C
Supply voltage: +4 V to +30 V recommended operating range
Output scale factor: +10 mV/°C nominal
Accuracy for LM35CA grade:
±0.2°C typical, ±0.5°C tested limit at 25°C
±0.4°C typical, ±1°C tested limit at high-temperature endpoint
±0.4°C typical, ±1.5°C design limit at low-temperature endpoint
Current drain: less than 60 µA feature value; LM35CA table shows 56 µA typical and 67 µA tested limit at VS = 5 V, 25°C
Output impedance: low impedance output; datasheet feature calls out 0.1 Ω for 1 mA load

Symbol / Pin Description Findings
Symbol has the correct three functional terminals: VS+, VOUT, and GND.
Pin numbering for VOUT and GND is swapped versus the TI datasheet.
All terminal Pin Type values are currently Unspecified; recommended pin typing is:
VS+ / pin 1: Power input
VOUT / pin 2: Analog output
GND / pin 3: Ground / power return
Footprint Findings
Pad count matches the datasheet: 3 leads.
The imported footprint appears to be a TO-92-style footprint, with Z03A text present.
Because the schematic pin numbers for VOUT and GND are swapped, the footprint pad mapping should be considered incorrect until pins 2 and 3 are corrected.
Recommended Corrections
Set the official Datasheet URL property to https://www.ti.com/lit/ds/symlink/lm35.pdf if/when a top-level part Datasheet field is available.
Change VOUT terminal Pin Number from 3 to 2.
Change GND terminal Pin Number from 2 to 3.
Set pin types/descriptions:
VS+ pin 1: positive supply input, +4 V to +30 V
VOUT pin 2: analog temperature output, 10 mV/°C
GND pin 3: ground/reference return
Re-check footprint pad numbering after the schematic pin-number correction.
